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.
Take the equation 7x = 0. Based on the zero product property, either 7 = 0 or x = 0. It is known that 7 cannot equal zero, therefore, x must equal zero. Now look at the equation xyz = 0. Even though there are three variables, you can separate the expression on the left side of the equation into two expressions.
