Use cofunction identities and trig identities to find the indicated trig functions
In this video series I show you how to use even and odd functions to evaluate trigonometric functions. Cosine and secant are our even functions where sine, tangent, cosecant and cotangent are our odd functions. cos(t) = 3/4. Find cos(-t)
