integral of (sqrt(1+\sqrt{z)})/(sqrt(z))

\int \frac{1 + z}{z} d z

\frac{4}{3} (1 + z)^{\frac{3}{2}} + C

Solution steps

\int \frac{1 + z}{z} d z

Apply u-substitution

: \int 2 u d u

= \int 2 u d u

Take the constant out:

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

= 2 \cdot \int u d u

Apply the Power Rule

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

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

Substitute back

u = 1 + z

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

Simplify

2 \cdot \frac{2}{3} (1 + z)^{\frac{3}{2}} : \frac{4}{3} (1 + z)^{\frac{3}{2}}

= \frac{4}{3} (1 + z)^{\frac{3}{2}}

Add a constant to the solution

= \frac{4}{3} (1 + z)^{\frac{3}{2}} + C

\int e^{- s x} cos (8 x) d x

\int \frac{x}{x ^{4} - 16 x ^{2} + 63} d x

\int - 10 3 - 2 x - x^{2} d x

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

\int (s^{2} + 1) (s^{3} + 3 s)^{4} d s
