Find the amplitude, if it exists, and the period of: y = tan(1/4·q). There is no "amplitude" for tangent, cotangent, secant, or cosecant functions. Only sines and cosines have amplitudes. But all have periods. 1. The period of y = A·sin(Bx), y = A·cos(Bx), y = A·sec(Bx), and y = A·csc(Bx) is |2p/B|. 2. The period of y = A·tan(Bx) and y = A·cot(Bx), is |p/B|. So the period of y = tan(1/4·q) is |p/(1/4)| = p÷(1/4) = p×(4/1) = 4p Edwin
