tan^2 = sin^2/cos^2
1 - sin^2 = cos^2
(1 + sin^2/cos^2)(cos^2) = cos^2 + sin^2 = 1
Thank you. Can you help me by checking my homework? I have a test coming up and want to make sure I'm understanding and doing this correctly before I take the test.
I'd like to but I'm kinda busy helping other students right now.
Ok thank you anyway :)
you bet :)
