$\int_{x}^{- 0.8} - 9 \tan (t) d t$

Step 1

Swap the bounds of integration.

$\frac{d}{d x} [- \int_{- 0.8}^{x} - 9 \tan (t) d t]$

Step 2

Take the derivative of $- \int_{- 0.8}^{x} - 9 \tan (t) d t$ with respect to $x$ using Fundamental Theorem of Calculus.

$- (- 9 \tan (x))$

Step 3

Multiply $- 9$ by $- 1$ .

$9 \tan (x)$
