integral of (x+y)^{1/2}

\int (x + y)^{\frac{1}{2}} d x

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

Solution steps

\int (x + y)^{\frac{1}{2}} d x

Apply u-substitution

= \int u^{\frac{1}{2}} d u

Apply the Power Rule

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

Substitute back

u = y + x

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

Add a constant to the solution

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

\int \frac{( x ^{3} - x ^{2} + 1 )}{( x ^{2} + 2 x + 2 ) ^{2}} d x

\int (sin^{3} (x)) (cos (x)) d x

\int 3 x (x^{2} - 2)^{5} d x

\int x^{2} (e^{x^{3}} + 3 x + 2) d x

\int 1 + (2 x (x^{2} + 1)^{\frac{1}{2}})^{2} d x
