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.
1 - When Qx = 0 you have a discontinuity (Because you can't divide by zero). 2 - To find the points of discontinuity she simply sets the denominator equal to zero and solves for the variable. 3 - You also have a vertical asymptote at these points UNLESS the numerator is also equal to zero.4 - If both the numberator and the demoniator equal zero at the same time... for the same value of X... - When Qx = 0 you have a discontinuity (Because you can't divide by zero). 2 - To find the points of discontinuity she simply sets the denominator equal to zero and solves for the variable. 3 - You also have a vertical asymptote at these points UNLESS the numerator is also equal to zero.
