SSE2 implementations of sin, cos, exp, log, tan, cot, atan, atan2 The sin, cos, exp and log functions were written by Julien Pommier (see unmodified sse_mathfun.h).

The graph of y = tan θ As the point P moves anticlockwise round the circle, the values of cos θ and sin θ change, therefore the value of tan θ will change. This graph has a period of 180°.

Pages Sin, cos and tan Before we can use trigonometric relationships we need to understand how to correctly label a right-angled triangle.

Hi, I've been working with sympy to use it on robot direct kinematics, however, it doesn't evaluate cos or sin functions, code attached below.
