1.) cot θ (theta) = 0.791, find sec θ and tan θ

2.) tan θ = 9/40, what is the value sin^2θ + cos^2θ

**Reiny**, Tuesday, November 26, 2013 at 11:48pmDo you not have a calculator?

if cotØ = .791

then tanØ = 1/.791 = appr 1.264

Ø = 51.656°

secØ = 1/cosØ = 1.612

2. sin^2 Ø + cos^2 Ø = 1 , one of the major trig identities, which you MUST know.
