$\frac{3}{2}\left(\frac{-\cos\left(x\right)^2+\sin\left(x\right)\left(1-\sin\left(x\right)\right)}{\cos\left(x\right)^2}\right)$

## Step-by-step explanation

Problem to solve:

$\frac{d}{dx}\left(\frac{3\left(1-\sin\left(x\right)\right)}{2\cos\left(x\right)}\right)$
1

Take $\frac{3}{2}$ out of the fraction

$\frac{d}{dx}\left(\frac{\frac{3}{2}\left(1-\sin\left(x\right)\right)}{\cos\left(x\right)}\right)$
2

Take out the constant from the fraction's numerator

$\frac{d}{dx}\left(\frac{3}{2}\left(\frac{1-\sin\left(x\right)}{\cos\left(x\right)}\right)\right)$

$\frac{3}{2}\left(\frac{-\cos\left(x\right)^2+\sin\left(x\right)\left(1-\sin\left(x\right)\right)}{\cos\left(x\right)^2}\right)$
$\frac{d}{dx}\left(\frac{3\left(1-\sin\left(x\right)\right)}{2\cos\left(x\right)}\right)$
