Asymptotes of Secant, Cosecant, and Cotangent
To find the x-intercepts and asymptotes of secant, cosecant, and cotangent, rewrite them in terms of sine and cosine. Notice that since secant and cosecant have 1 in the numerator and a trig function in the denominator, they can never equal zero; they do not have x-intercepts. The vertical asymptotes of the three functions are whenever the denominators are zero.

In this video we look at the reciprocal ratios: tan, cot, csc,and sec. Specifically, how to determine the period and find the asymptotes.
