Homework Help: Math

Eliminate the parameter and write the corresponding rectangular equation whose graph represents the curve.

x = sec Q
y = cos Q

x^2 + y^2 = 1/cos^2 + sin^2/cos^2 =
x^2(1 +sin^2) = x^2(2-cos^2)

x^2(2-1/x^2) = 2x^2 - 1

x^2 - y^2 = 1

My teacher said to use secant*cosine = 1. Please explain!!
