ok you can verify it like this: 1 + tan^2 equals sec^2 . That is an identity that is already proven, so you can use it. When you substitute it on your equation, you'll get: sec^2 / sin^2 + cos ^2 = sec^2 . You need to drop the sin^2 + cos^2 . There is another identity that you need to memorize that tells us that: sin^2 + cos^2 = 1. Then you substitute all and you`ll get: sec^2 / 1 = sec ^2. Then you have already verified it!! So remember to memorize this two equations:

1 + tan ^2 = sec ^2 and sin^2 + cos^2 = 2.

Good luck!

First, you need to change all of the variables to one. Then you can figure it out.
