These functions are abbreviated as sin, cos, and tan respectively. These functions are particularly useful when dealing with right triangles and the unit circle. The trigonometric functions can help solve for missing sides and angles in a triangle. Often, the Pythagorean Theorem is also useful to...

正弦和余弦就像好朋友:一个跟着另一个,隔开的距离是刚好 "π/2" 弧度(90°)。 正切函数 的图 正切的图有完全不同的形状……它处于正与负无穷大之间,每π弧度(180°)经过 0 一次,像这样: 在π/2 弧度(90°),和 -π/2、3π/2 等等,正切函数是未定义的,因为它可以是正无穷大或负无穷大。
