# Math Help - Quick question about tangent and cotangent.

1. ## Quick question about tangent and cotangent.

Is the following true?

$tan^2 x = \frac{sin^2 x}{cos^2 x}$

$cot^2 x = \frac{cos^2 x}{sin^2 x}$

If so, then I've solved an identity. If not, back to the drawing board!

2. Yes. Both are true.
