Graphs of CSC(X) and SEC(X) By Rithirong Thandee
What is CSC(X) and SEC(X)? • CSC(X) = 1/SIN(X) • SEC(X) = 1/COS(X)
Graphing SIN(X) and COS(X) • Use these formulas • SIN(X): aSIN(bX) • COS(X): aCOS(bX) • Amplitude = IaI • Period = 2π/b

Y = 3CSC(2X) • Period = π Amplitude = I3I
Y = -SEC(X/2) • Period = 4π Amplitude = I1I
