Learn Japanese: It Isn’t More Difficult Than Any Other Language 5 Tips for Learning Japanese So What is the Best Way to Learn Japanese for English Speakers?The writing systems in Japanese are often seen as insurmountable challenge to chose who speak English or use the Latin Alphabet.

It doesn't matter if it is a European language such as French, Spanish, or Portuguese, or a language that doesn't use the Latin alphabet, such as Arabic, Korean, Mandarin Chinese, or Japanese.As often happens, people see the artistic nature of the Chinese characters used in Japanese kanji and they have no idea where to start.

Let's find out...But your language learning will need to go beyond just studying Japanese grammar. In order to speak to Japanese people in their native language you will also need to learn about Japanese culture, too. But don't worry, whilst studying Japanese, you will learn about the culture, and vice-versa.Take a Japanese tutor to help you. Should You Take a JLPT Exam?The JLPT (Japanese-Language Proficiency Test) is the official exam for establishing your level in Japanese. There are two qualifications:JLPT 1: The highest of the two levels.JLPT 2.There are many people who say that passing the JLPT 1 means that you’re fluent. However, no qualification is perfect.  The JLPT is a listening and reading exam. At no point do you actually have to speak Japanese. You can pass the exam just by listening, understanding, and reading, but as you probably know, speaking is one of the most demanding parts of learning a language, and this test doesn't test your Japanese pronunciation skills.Passing a test to prove your level can do wonders for your career.

While people often say that the most difficult languages to learn are those that don't use the Latin alphabet, this only affects the reading and writing aspects. Speaking is no more difficult than any other language, and speaking Japanese can be really easy if you know where to begin.A lot of people say that English is really difficult to learn, after all. It really depends on your point of view. While the Latin alphabet might seem simpler, English can be much harder to read because how words are pronounced has no relation to the letters written on the page.At the end of the day all languages are a mixture of verbs, nouns, adjectives, tenses, but to name a few. This means they all have the same ingredients, it is just the way that they are used which differs.Although you can learn Japanese independently, it would be helpful to have someone to whom you can ask questions if you do get stuck.But if you do everything right, there is no reason learning Japanese should be harder or easier than most other languages. If you want to learn Chinese, it is also considered difficult due to all the characters used in its writing system which Japan has borrowed for its kanji. On the other hand, while Chinese grammar can be quite simple, there are 4 different tones you have to learn.What about Japanese, then? It’s a difficult language to read and write. As we said, learning kanji is no walk in the park. However, learning how to speak Japanese can be much simpler than learning to speak English.Children learn to speak long before they learn to write. (Source: pixabay.com)Start by learning to speak Ja panese. In addition to being far more rewarding, it’s a great way to get yourself motivated before you start learning to write it. It’s pretty sound logic. Everyone learns to speak before they learn to write, after all. It would be weird to see a Japanese person who could read and write perfectly in English but not speak a word, wouldn’t it? It’d be almost impossible for them to find a job. There’s no reason you should do the same. 5 Tips for Learning JapaneseThere is plenty of advice for learning Japanese on the internet. In order to overcome the perceived difficulty of Japanese, make the most of this advice as it is designed to help you succeed. Here are a few things to bear in mind:Be motivated: when it comes to learning a language, motivation is one of the most important factors. Why do you want to learn Japanese? Do you want to travel to Japan? Work in Kyoto? Wow your friends? Whatever your reasons for learning Japanese, they need to be enough to ensure that you remai n motivated in the long term. You can’t learn a second language in just a few weeks or without a lot of hard work and consistency. If you don’t have the time to put in the effort, you may as well not even start.Expose yourself to as much of the language as possible:  With anime, manga, video games, and J-pop, you’re spoiled for choice in terms of Japanese-language media. Even if you don’t understand at the start, listening is the cornerstone of learning a language.  Exposure to a Japanese language environment will help your ear get used to the sounds, tones, pronunciation, and the syntax used in everyday Japanese sentences (think of a japanese language course london). In linguistics, this is known as the input. This is the stage of learning where we store information. The more you input, the easier it is to move on to the output stage. This is when you start saying everything you’ve assimilated.Find a Japanese mentor: Ideally, you should be looking for a Japanese native sp eaker to practice with who can help you speak as much Japanese as possible. Of course, you could still hang out with a non-native speaker. They can help you to practice regularly, learn about Japanese etiquette, and correct your pronunciation. Finding a Japanese teacher is also a good idea as they can help you how to learn the more complicated stuff.Speak, speak, and speak: The output stage is an essential part of learning a language. No matter what language you’re learning, listening and reading isn’t enough, you have to talk! Even if you make mistakes, it doesn’t matter. It’s better than just repeating an expression in your head and never saying it because you’re scared of making a mistake. If you never speak, who’ll correct your mistakes? You can’t expect to become perfectly bilingual without ever daring to speak. Making mistakes and forgetting words is an integral part of learning a language that you can’t skip.Learn the kana: kana (both hiragana and katakana) ar e part of the Japanese writing, and are essential for even basic Japanese. If you want to move onto writing in Japanese, you’ll have to at least learn these systems by heart. You can’t study Japanese writing without this step. So What is the Best Way to Learn Japanese for English Speakers?Undoubtedly the best way to learn is with a native speaker. And if you move to a Japanese speaking environment, you will learn faster.As a new learner, there are a number of books to learn Japanese, and you might even be tempted to take an online Japanese course. But with these options you are unlikely to experience the accent, not to mention having no support if you run into difficulties.For a long time, Japanese was thought to be an isolated language with no other languages related to it, until a relationship to Ryukyuan languages was established. However, since it has no relation to English, it can make it harder to read and write than European languages. But different languages have differe nt challenges, and this particular one doesn't make Japanese any harder or easier to learn than other languages.Find yourself a Japanese mentor in order to learn about Japanese culture. (Source: stock.tookapic.com)With that said, it’s probably a good idea to take Japanese lessons when you first start.If you want to start speaking right from the get-go, you should look for a Japanese course or teacher who’s happy to do that. There are plenty of teachers who are happy to focus on speaking.Do you remember your languages classes from school? Can you still “speak” that language? Most people will probably say “no” because the classes focused on passing tests by reading and writing.In short:Just because writing Japanese is difficult, that doesn’t mean you shouldn’t learn it. Speaking Japanese can be a lot easier than several other languages.It’s no harder for a native English speaker to learn than any other language, really. Japanese can be really easy to pronounce becaus e there are so few vowels and a lot fewer than there are in English.It’s not really necessary to take the JLPT since there aren't many people will ask for it and it doesn’t test speaking, which is probably one of the most important aspects when it comes to working in any given language.With a lot of hard work, you can learn to speak Japanese. Start by trying to memorize a few Japanese words and phrases in order to build your confidence.

Composite Function

Composite Function Composite Functions is the application of one function to the results of another function. Composition functions will not be commutative. This commutatively is attained only by particular functions and in special circumstances. Derivatives of compositions that involve differentiable functions can be found using the chain rule. Suppose result of 1st function f (x) is applied into the 2nd function g (x), this composite function is written as g(f(x)) or (g?f) (x). Composite functions are combination of 2 or more functions. We can say that it is a function that is expressed in terms of one or more functions. It may be noted that, (f?g)(x) (g?f)(x). Example 1: Simplify by Composite function f(x) = 2x + 3 Solution: First we will apply f and then apply f to that result = (f?f)(x) = f(f(x)) = (f ? f) (x) = 2 (2x + 3) + 3 = 4x + 9 = f ( f (x) ) = f (2x + 3) = 2 (2x + 3) + 3 = 4x + 9 Example 2: If f(x) = 2x and g(x) = 2^x, then what is (f ? g) (x)? Solution: The given problem we have = F(x) = 2x and g (x) = 2^x = When we do composite function (f ? g) (x) we get = (f ? g) (x) = f ( g ( x ) ) = f (2^x) = And f (2^x) = 2 . 2^x = 2^ (x + 1) = Answer: (f ? g) (x) = 2^ (x + 1)
