• Lesson
  4.6 Graphing Cosecant and Secant Functions
  
  1. Graph the reciprocal functions as an outline
  2. Graph a vertical asymptote where the sine or cosine function has an intercept (where sin(x) = 0 because csc(x) = 1/sin(x) = 1/0 UNDEFINED. Similarly for cosine and secant)
  3. Where the sine or cosine function has a max, cosecant or secant has a local min. Where sine or cosine function has a min, cosecant or secant has a local max.
