tan (50) - \frac{sin (50)}{cos (50)}

$\tan (50) - \frac{\sin (50)}{\cos (50)}$

Step 1

Rewrite

tan (50)

$\tan (50)$ in terms of sines and cosines.

\frac{sin (50)}{cos (50)} - \frac{sin (50)}{cos (50)}

$\frac{\sin (50)}{\cos (50)} - \frac{\sin (50)}{\cos (50)}$

Step 2

Combine the numerators over the common denominator.

\frac{sin (50) - sin (50)}{cos (50)}

$\frac{\sin (50) - \sin (50)}{\cos (50)}$

Step 3

Subtract

sin (50)

$\sin (50)$ from

sin (50)

$\sin (50)$ .

\frac{0}{cos (50)}

$\frac{0}{\cos (50)}$

Step 4

Divide

0

$0$ by

cos (50)

$\cos (50)$ .

0

$0$
