Practice is the app "trigonometric ratio, trigonometric functions (sin · cos · tan)" of high school mathematics. Asking the value of a trigonometric ratio to corner radian measure of (0 ~ 2π radians) and (180 ° 0 ° ~) frequency method, I can transform practice of reducing official. It is useful to widely exam math foundations of the college entrance examination from the regular examination measures of high school. As you repeatedly practice, and come to be more and more quickly answer, sin · cos · tan will be good.* There is a practice for the content of the following four in this app· (0 ° ~ degree measure 180 °) the value of the trigonometric ratio· (0 ~ 2π radian radian measure) value of trigonometric ratio· (90 ° or 180 ° degree measure) reducing officialAnd reduction official (radian measure or (π π / 2 radians)
