Graphing Secant and Cosecant
Date:___________
Cosecant is the reciprocal of the SINE
function so graph the sine function first.
Secant is the reciprocal of the COSINE
function, so graph the cosine function first.
A vertical asymptote will occur every time the function crosses the midline.
Always label your critical values on your x­ and y­ axis.
