SOLUTION: Verify: sec^2x-sin^2x-cos^2x = tan^2x Really need help on this. It breaks down as 1/cos^2x-sin^2x-cos^2x = tan^2x but I get stuck after this point.

Question 881541: Verify: sec^2x-sin^2x-cos^2x = tan^2x
Really need help on this.
It breaks down as 1/cos^2x-sin^2x-cos^2x = tan^2x but I get stuck after this point.

You can put this solution on YOUR website!
Verify: sec^2x-sin^2x-cos^2x = tan^2x
sec%5E2%28x%29-sin%5E2%28x%29-cos%5E2%28x%29
sec%5E2%28x%29-%28sin%5E2%28x%29%2Bcos%5E2%28x%29%29
sec%5E2%28x%29-1
