$\int t^{\frac{3}{2}} + 2 t^{\frac{1}{2}} - 4 t^{- \frac{1}{2}} d t$

Step 1

Split the single integral into multiple integrals.

$\int t^{\frac{3}{2}} d t + \int 2 t^{\frac{1}{2}} d t + \int - 4 t^{- \frac{1}{2}} d t$

Step 2

By the Power Rule, the integral of $t^{\frac{3}{2}}$ with respect to $t$ is $\frac{2}{5} t^{\frac{5}{2}}$ .

$\frac{2}{5} t^{\frac{5}{2}} + C + \int 2 t^{\frac{1}{2}} d t + \int - 4 t^{- \frac{1}{2}} d t$

Step 3

Since $2$ is constant with respect to $t$ , move $2$ out of the integral.

$\frac{2}{5} t^{\frac{5}{2}} + C + 2 \int t^{\frac{1}{2}} d t + \int - 4 t^{- \frac{1}{2}} d t$

Step 4

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

$\frac{2}{5} t^{\frac{5}{2}} + C + 2 (\frac{2}{3} t^{\frac{3}{2}} + C) + \int - 4 t^{- \frac{1}{2}} d t$

Step 5

Since $- 4$ is constant with respect to $t$ , move $- 4$ out of the integral.

$\frac{2}{5} t^{\frac{5}{2}} + C + 2 (\frac{2}{3} t^{\frac{3}{2}} + C) - 4 \int t^{- \frac{1}{2}} d t$

Step 6

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

$\frac{2}{5} t^{\frac{5}{2}} + C + 2 (\frac{2}{3} t^{\frac{3}{2}} + C) - 4 (2 t^{\frac{1}{2}} + C)$
