Mô tả chuyển động của các thiên thể bằng các hàm sin và cos.

In this section we focus on their behavior as functions and study their graphs. The graphs of sinx, cosx, and tanx are given below, where x must be in radians. tanx = sinx/cosx. This identity can easily be shown by asking the student to draw a right-angled triangle, with one of the remaing two angles labelled x. Algorithm 282: Derivatives of ex/x, cos (x)/x, AND sin (x)/x.

The integration of sin x cos x yields (-1/4) cos 2x + C as the integral of sin x cos x using the sin 2x formula of trigonometry. sinx cosx關係. Author:陳柄何.
