Do 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.
Could someone please help me with the following q's I'm having some trouble:
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
