    :delim: |

	float cos(float)| Cosine trig function.
	float sin(float)| Sine trig function. 
	float tan(float)| Tangent trig function.
	float acos(float)| Inverse cosine trig function.
	float asin(float)| Inverse sine trig function. 
	float atan(float)| Inverse tangent trig function.
	float atan2(float,float)|Calculates the inverse of the trigonometric function tangent. The input is the y and x proportions. The returned angle is given in radian.
