$\frac{\tan (x) + 1}{\cot (x) + 1} = \frac{\sin (x)}{\cos (x)}$

Step 1

Convert from $\frac{\sin (x)}{\cos (x)}$ to $\tan (x)$ .

$\frac{\tan (x) + 1}{\cot (x) + 1} = \tan (x)$

Step 2

Graph each side of the equation. The solution is the x-value of the point of intersection.

$x \approx 0, 0.1, \frac{1}{5}, 0.3, \frac{2}{5}, - \frac{1}{2}, - \frac{3}{5}$
