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.
Therefore, x = 2 Â· cos (â60Â°) = 2 Â· cos 60Â° = 2 Â· Â½ = 1. y = 2 Â· sin (â60Â°) = 2(âsin 60Â°) = 2(âÂ½) = â . Proof of the main theorem. A function of any angle will equal plus or minus that same function. of the corresponding acute angle.The sign will depend on the quadrant.he corresponding acute angle of 135Â° is 45Â°. In the second quadrant, the cosine is negative and the sine is positive. Therefore, x = r cos Î¸ = 1 Â· cos 135Â° = âcos 45Â° = âÂ½ .
