integral of (sqrt(x-1))

\int (x - 1) d x

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

Solution steps

\int x - 1 d x

Apply u-substitution

: \int u d u

= \int u d u

Apply the Power Rule

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

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

Substitute back

u = x - 1

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

Add a constant to the solution

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

\int - \frac{1}{r} d r

\int \frac{7 x + 2}{1 - 25 x ^{2}} d x

\int 7 x^{3} 9 - x^{2} d x

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

\int (x + 9)^{4} d x
