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.
In a right triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the opposite side. In a formula, it is abbreviated to just 'csc'.Of the six possible trigonometric functions, cosecant, cotangent, and secant, are rarely used.ngles greater than 90Â°. In a right triangle, the two variable angles are always less than 90Â° (See Interior angles of a triangle). But we can in fact find the cosecant of any angle, no matter how large, and also the cosecant of negative angles. For more on this see Functions of large and negative angles.
