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 The number of hydrogen atoms that can be bonded to a given number of carbon atoms is limited by the valence of carbon. 2  For compounds of carbon and hydrogen (hydrocarbons) the maximum number of hydrogen atoms that can be bonded to n carbons is 2n + 2 (n is an integer).3  In the case of methane, CH 4, n=1 & 2n + 2 = 4.
