integral of 3/2 sqrt(x+1)

\int \frac{3}{2} x + 1 d x

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

Solution steps

\int \frac{3}{2} x + 1 d x

Take the constant out:

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

= \frac{3}{2} \cdot \int x + 1 d x

Apply u-substitution

: \int u d u

= \frac{3}{2} \cdot \int u d u

Apply the Power Rule

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

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

Substitute back

u = x + 1

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

Simplify

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

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

Add a constant to the solution

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

sin (6 (t - \frac{3 π}{6}) + 3 π)

\frac{d y}{d x} = \frac{e ^{x - y}}{1 + e ^{x}}

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

f (x) = x^{2} - 5 x, at x = - 2

\int 9 x sin (x) cos (x) d x
