Simplify with factoring out.

Tap for more steps...

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

$\frac{4 \cos (1)}{- 1 + \cos^{2} (1)}$

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

$\frac{4 \cos (1)}{- 1 (1) + \cos^{2} (1)}$

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

$\frac{4 \cos (1)}{- 1 (1) - 1 (- \cos^{2} (1))}$

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

$\frac{4 \cos (1)}{- 1 (1 - \cos^{2} (1))}$

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

$\frac{4 \cos (1)}{- (1 - \cos^{2} (1))}$

Apply pythagorean identity.

$\frac{4 \cos (1)}{- \sin^{2} (1)}$

Factor $\sin (1)$ out of $\sin^{2} (1)$ .

$\frac{4 \cos (1)}{- (\sin (1) \sin (1))}$

Separate fractions.

$\frac{4}{- (\sin (1))} \cdot \frac{\cos (1)}{\sin (1)}$

Convert from $\frac{\cos (1)}{\sin (1)}$ to $\cot (1)$ .

$\frac{4}{- (\sin (1))} \cot (1)$

Separate fractions.

$\frac{4}{- 1} \cdot \frac{1}{\sin (1)} \cot (1)$

Convert from $\frac{1}{\sin (1)}$ to $\csc (1)$ .

$\frac{4}{- 1} \csc (1) \cot (1)$

Divide $4$ by $- 1$ .

$- 4 \csc (1) \cot (1)$

Evaluate $\csc (1)$ .

$- 4 \cdot 57.29868849 \cot (1)$

Multiply $- 4$ by $57.29868849$ .

$- 229.19475399 \cot (1)$

Evaluate $\cot (1)$ .

$- 229.19475399 \cdot 57.28996163$

Multiply $- 229.19475399$ by $57.28996163$ .

$- 13130.55866229$

The result can be shown in multiple forms.
