Where does the cosecant graph come from?
👉 Learn the basics of graphing the secant and the cosecant graphs. Recall that the secant is the reciprocal of the cosine while the cosecant is the reciprocal of the sine. Also recall that the cosine graph is a sinusoidal graph with x-intercepts at x = n*pi/2, maximum value of 1 at x = 2n*
