I integration is quite difficult to learn in mathematics III high school.
"Integral drill" is an app that help the study of the integration.
However, it is not in the app to study the integration from zero. It is an application for people who are learning the basics of differential and integral of mathematics III of high school students already is further study.
Function There are two roughly. One is "drill", another is "Search".
In the "drill",
First, look at the issues that have been displayed on the screen, try solving actually on top of the note. (← indeed this need paper and pencil!)
Then we will answer the alignment. If necessary, how to solve, please also look at. If the correct answer is "solved was", and then press the "could not solve" if mistake.
Doing this, we will solve the problem entirely. This is a drill.
At the start the first has become to the rank of "first stage". You can receive Ascent test to clear the condition. And, (even to say that, it is a self-scoring, but ...) If you clear the dan test, two-stage, it will be able to continue to Ascent with the three-stage.
Then, after Ascent to Kudan, when finished solve all the problems, and finally there is a dan test to the "master". If clear This is can become the "master".
Well, the other one of the functions is "Search". In the "Search",
Level, the search expression, how to solve the integral of the problems or the like, this function can be examined how to solve.
The designation of "level", it will be able to make the designation, such as "challenge level of the problem."
The designation of "Expressions", "have entered the trigonometric functions in the denominator, the problem is included logarithmic function", you will be able to search, such as.
The designation of "how to solve", it will be able to "contain the replacement integration and partial integration problem", the like of the search.
By combining these, for example, it can also be a search like "challenge with have a replacement integration they contain a trigonometric problems". (However, there may be even less the designation, there is no such problem ...)
Problem in this app has been recorded more than 200 questions.
※ Note ※ In one of the problem, you may figure out how to solve is several ways. (There is also a problem that put the actual number of different solutions.)
Solution that is put is the best, because it does not mean that everyone is in the case where solved in the solution other than the method, as you choose as a result, the best solve easy way to try compared with respect to everyone of how to solve Please be in. (If necessary, please do duck the guidance of math teacher)
