Cotangent Graph

This video provides an example of graphing the cotangent function with a different period and a vertical stretch.

Cotangent is the reciprocal trig function of tangent function and can be defined as cot(theta) = cos(theta)/sin(theta). It is an odd function, meaning cot(−theta) = −cot(theta), and it has the property that cot(theta + pi) = cot(theta). Because sine is the denominator, and the function is undefined when sin(theta) = 0, the cotangent graph has vertical asymptotes at all integer multiples of pi, when sin(theta) = 0.
