目力 数学トレーニング

It is an application that you can intensively train "it" and "computation technique" useful in mathematics of college entrance examinations intensively. It is carefully selected and posted what is blind in spite of efficient headache.

■ Introduction of application contents ■

By looking at the problem that appeared on the screen, I will imagine "from solution to conclusion" with eyes and head without taking notes.

The problem is gathered for each theme, and as you tap the button, problems with converted numerical values ​​etc. are automatically created and displayed automatically.

Therefore, learners can train imagination and mental computing power by repeatedly practicing intensively repeated themes that they want to train.

"Practice" and "Practical edition" are prepared.

In "Practice", an animation that briefly explains the answer for each question is displayed. Also, when you tap a button at any time, new problems are automatically generated, so you can practice without any restrictions in mind.

In "Real Warfare", measure the time to solve 10 questions for each theme. The best record is saved for each theme.

■ Content and level of problem ■

Among the mathematical problems of college entrance examinations, especially the part which difference is caused by image power and the instantaneous power of calculation is extracted, and even if it knows only the knacks, it is reasonable from the solution method to the conclusion though the memorandum is not taken It is something that can be done.

The theme being treated is as follows.

· Moving ratio by parallel line 【Number A "Nature of figure"】 (Free)

· Line segments cut off by parabola 【Number I "Quadratic function"】 (Free)

· Cubic function graph and tangent 【Number II "Cubic function"】 (Paid 120 yen)

· Σ (linear equation) 【Number B "Sequence"】 (120 yen charged)

· Inequality including absolute value symbol 【Number I "Numbers and expressions"】 (Paid 120 yen)

It will be updated from time to time
