$f (x) = \frac{x^{2}}{4} + \frac{2}{3 x^{2}} - \sqrt{x} + π$

Step 1

The function $F (x)$ can be found by finding the indefinite integral of the derivative $f (x)$ .

$F (x) = \int f (x) d x$

Step 2

Set up the integral to solve.

$F (x) = \int \frac{x^{2}}{4} + \frac{2}{3 x^{2}} - \sqrt{x} + π d x$

Step 3

Split the single integral into multiple integrals.

$\int \frac{x^{2}}{4} d x + \int \frac{2}{3 x^{2}} d x + \int - \sqrt{x} d x + \int π d x$

Step 4

Since $\frac{1}{4}$ is constant with respect to $x$ , move $\frac{1}{4}$ out of the integral.

$\frac{1}{4} \int x^{2} d x + \int \frac{2}{3 x^{2}} d x + \int - \sqrt{x} d x + \int π d x$

Step 5

By the Power Rule, the integral of $x^{2}$ with respect to $x$ is $\frac{1}{3} x^{3}$ .

$\frac{1}{4} (\frac{1}{3} x^{3} + C) + \int \frac{2}{3 x^{2}} d x + \int - \sqrt{x} d x + \int π d x$

Step 6

Since $\frac{2}{3}$ is constant with respect to $x$ , move $\frac{2}{3}$ out of the integral.

$\frac{1}{4} (\frac{1}{3} x^{3} + C) + \frac{2}{3} \int \frac{1}{x^{2}} d x + \int - \sqrt{x} d x + \int π d x$

Step 7.1

Move $x^{2}$ out of the denominator by raising it to the $- 1$ power.

$\frac{1}{4} (\frac{1}{3} x^{3} + C) + \frac{2}{3} \int {(x^{2})}^{- 1} d x + \int - \sqrt{x} d x + \int π d x$

Step 7.2.1

Apply the power rule and multiply exponents, ${(a^{m})}^{n} = a^{m n}$ .

$\frac{1}{4} (\frac{1}{3} x^{3} + C) + \frac{2}{3} \int x^{2 \cdot - 1} d x + \int - \sqrt{x} d x + \int π d x$

Step 7.2.2

Multiply $2$ by $- 1$ .

$\frac{1}{4} (\frac{1}{3} x^{3} + C) + \frac{2}{3} \int x^{- 2} d x + \int - \sqrt{x} d x + \int π d x$

Step 8

By the Power Rule, the integral of $x^{- 2}$ with respect to $x$ is $- x^{- 1}$ .

$\frac{1}{4} (\frac{1}{3} x^{3} + C) + \frac{2}{3} (- x^{- 1} + C) + \int - \sqrt{x} d x + \int π d x$

Step 9

Since $- 1$ is constant with respect to $x$ , move $- 1$ out of the integral.

$\frac{1}{4} (\frac{1}{3} x^{3} + C) + \frac{2}{3} (- x^{- 1} + C) - \int \sqrt{x} d x + \int π d x$

Step 10

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{x}$ as $x^{\frac{1}{2}}$ .

$\frac{1}{4} (\frac{1}{3} x^{3} + C) + \frac{2}{3} (- x^{- 1} + C) - \int x^{\frac{1}{2}} d x + \int π d x$

Step 11

By the Power Rule, the integral of $x^{\frac{1}{2}}$ with respect to $x$ is $\frac{2}{3} x^{\frac{3}{2}}$ .

$\frac{1}{4} (\frac{1}{3} x^{3} + C) + \frac{2}{3} (- x^{- 1} + C) - (\frac{2}{3} x^{\frac{3}{2}} + C) + \int π d x$

Step 12

Apply the constant rule.

$\frac{1}{4} (\frac{1}{3} x^{3} + C) + \frac{2}{3} (- x^{- 1} + C) - (\frac{2}{3} x^{\frac{3}{2}} + C) + π x + C$

Step 13.1

Combine $\frac{2}{3}$ and $x^{\frac{3}{2}}$ .

$\frac{1}{4} (\frac{1}{3} x^{3} + C) + \frac{2}{3} (- x^{- 1} + C) - (\frac{2 x^{\frac{3}{2}}}{3} + C) + π x + C$

Step 13.2

Simplify.

$\frac{x^{3}}{12} - \frac{2}{3 x} - \frac{2 x^{\frac{3}{2}}}{3} + π x + C$

Step 14

Reorder terms.

$\frac{1}{12} x^{3} - \frac{2}{3 x} - \frac{2}{3} x^{\frac{3}{2}} + π x + C$

Step 15

The answer is the antiderivative of the function $f (x) = \frac{x^{2}}{4} + \frac{2}{3 x^{2}} - \sqrt{x} + π$ .

$F (x) =$ $\frac{1}{12} x^{3} - \frac{2}{3 x} - \frac{2}{3} x^{\frac{3}{2}} + π x + C$
