Trigonometry from wolfram mathworld. The study of angles and of the angular relationships of planar and threedimensional figures is known as trigonometry. The trigonometric functions (also called the circular functions) comprising trigonometry are the cosecant cscx, cosine cosx, cotangent cotx, secant secx, sine sinx, and tangent tanx. The inverses of these functions are denoted csc^(1)x, cos^(1)x, cot^(1)x, sec^(1)x, sin.
