Donald John Trump (born June 14, 1946) is the 45th and current President of the United States, in office since January 20, 2017. Before entering politics, he was a businessman and television personality.
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.
we discuss the four other trigonometric functions: tangent, cotangent, secant, and cosecant. Each of these functions are derived in some way from sine and cosine. The tangent of x is deï¬ned to be its sine divided by its cosine: tanx = sinx cosx: The cotangent of x is deï¬ned to be the cosine of x divided by the sine of x: cotx = cosx sinx:
