$r = \tan (x) \sec (x)$

Step 1

Differentiate both sides of the equation.

$\frac{d}{d ?} (r) = \frac{d}{d ?} (\tan (x) \sec (x))$

Step 2

The derivative of $r$ with respect to $?$ is $r'$ .

$r'$

Step 3

Since $\tan (x) \sec (x)$ is constant with respect to $?$ , the derivative of $\tan (x) \sec (x)$ with respect to $?$ is $0$ .

$0$

Step 4

Reform the equation by setting the left side equal to the right side.

$r' = 0$

Step 5

Replace $r'$ with $\frac{d r}{d ?}$ .

$\frac{d r}{d ?} = 0$
