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.
Consider a call option and a put option with the same strike K for expiry at the same date T on some stock S, which pays no dividend.We assume the existence of a bond that pays 1 dollar at maturity time T. The bond price may be random (like the stock) but must equal 1 at maturity.utâcall parity implies: 1  Equivalence of calls and puts: Parity implies that a call and a put can be used interchangeably in any delta-neutral portfolio. 2  If is the call's delta, then buying a call, and selling shares of stock, is the same as selling a put and buying shares of stock.
