Step 1

Simplify with factoring out.

Tap for more steps...

Step 1.1

Reorder $\cos^{2} (C)$ and $- 1$ .

$- 1 + \cos^{2} (C)$

Step 1.2

Rewrite $- 1$ as $- 1 (1)$ .

$- 1 (1) + \cos^{2} (C)$

Step 1.3

Factor $- 1$ out of $\cos^{2} (C)$ .

$- 1 (1) - 1 (- \cos^{2} (C))$

Step 1.4

Factor $- 1$ out of $- 1 (1) - 1 (- \cos^{2} (C))$ .

$- 1 (1 - \cos^{2} (C))$

Step 1.5

Rewrite $- 1 (1 - \cos^{2} (C))$ as $- (1 - \cos^{2} (C))$ .

$- (1 - \cos^{2} (C))$

Step 2

Apply pythagorean identity.

$- \sin^{2} (C)$
