integral of sqrt(1+u)

\int 1 + u d u

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

Solution steps

\int 1 + u d u

Apply u-substitution

= \int v d v

Apply the Power Rule

= \frac{2}{3} v^{\frac{3}{2}}

Substitute back

v = 1 + u

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

Add a constant to the solution

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