Reciprocal Trigonometric Functions
There are three reciprocal trigonometric functions, making a total of six including cosine, sine, and tangent. The reciprocal cosine function is secant: sec(theta) = 1/cos(theta). The reciprocal sine function is cosecant, csc(theta) = 1/sin(theta). The reciprocal tangent function is cotangent, expressed two ways: cot(theta) = 1/tan(theta) or cot(theta) = cos(theta)/sin(theta).
