integral of sqrt(3x+1)

\int 3 x + 1 d x

\frac{2}{9} (3 x + 1)^{\frac{3}{2}} + C

Solution steps

\int 3 x + 1 d x

Apply u-substitution

: \int \frac{u}{3} d u

= \int \frac{u}{3} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{3} \cdot \int u d u

Apply the Power Rule

: \frac{2}{3} u^{\frac{3}{2}}

= \frac{1}{3} \cdot \frac{2}{3} u^{\frac{3}{2}}

Substitute back

u = 3 x + 1

= \frac{1}{3} \cdot \frac{2}{3} (3 x + 1)^{\frac{3}{2}}

Simplify

\frac{1}{3} \cdot \frac{2}{3} (3 x + 1)^{\frac{3}{2}} : \frac{2}{9} (3 x + 1)^{\frac{3}{2}}

= \frac{2}{9} (3 x + 1)^{\frac{3}{2}}

Add a constant to the solution

= \frac{2}{9} (3 x + 1)^{\frac{3}{2}} + C

n = 0 \sum \infty (- \frac{2}{7})^{n}

x^{2} - 4 x + 1, - x + 5

x \to 2 lim (15)

\int e^{- 6 t} d t

x + y \cdot y^{^{'}} = 0
