$\int_{- 2}^{2} (x^{3} \cos (\frac{x}{2}) + \frac{1}{2}) \sqrt{4 - x^{2} d x} d x$

Step 1

Raise $x$ to the power of $1$ .

$\frac{d}{d x} [\int_{- 2}^{2} (x^{3} \cos (\frac{x}{2}) + \frac{1}{2}) \sqrt{4 - 1 d (x^{2} x^{1})} d x]$

Step 2

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$\frac{d}{d x} [\int_{- 2}^{2} (x^{3} \cos (\frac{x}{2}) + \frac{1}{2}) \sqrt{4 - 1 d x^{2 + 1}} d x]$

Step 3.1

Add $2$ and $1$ .

$\frac{d}{d x} [\int_{- 2}^{2} (x^{3} \cos (\frac{x}{2}) + \frac{1}{2}) \sqrt{4 - 1 d x^{3}} d x]$

Step 3.2

Rewrite $- 1 d$ as $- d$ .

$\frac{d}{d x} [\int_{- 2}^{2} (x^{3} \cos (\frac{x}{2}) + \frac{1}{2}) \sqrt{4 - d x^{3}} d x]$

Step 3.3

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{4 - d x^{3}}$ as ${(4 - d x^{3})}^{\frac{1}{2}}$ .

$\frac{d}{d x} [\int_{- 2}^{2} (x^{3} \cos (\frac{x}{2}) + \frac{1}{2}) {(4 - d x^{3})}^{\frac{1}{2}} d x]$

Step 4

Once $\int_{- 2}^{2} (x^{3} \cos (\frac{x}{2}) + \frac{1}{2}) {(4 - d x^{3})}^{\frac{1}{2}} d x$ has been evaluated, it will be constant with respect to $x$ , so the derivative of $\int_{- 2}^{2} (x^{3} \cos (\frac{x}{2}) + \frac{1}{2}) {(4 - d x^{3})}^{\frac{1}{2}} d x$ with respect to $x$ is $0$ .
