$\log (a) \cdot \frac{\sin (a)}{\cos (a)} \cdot \cos (\frac{a}{\sin (a)})$

Step 1

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

$\log (a) \cdot \tan (a) \cdot \cos (\frac{a}{\sin (a)})$

Step 2

Separate fractions.

$\log (a) \tan (a) \cdot \cos (\frac{a}{1} \cdot \frac{1}{\sin (a)})$

Step 3

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

$\log (a) \tan (a) \cdot \cos (\frac{a}{1} \csc (a))$

Step 4

Divide $a$ by $1$ .

$\log (a) \tan (a) \cos (a \csc (a))$
