integral of 2sqrt(x-1)

\int 2 x - 1 d x

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

Solution steps

\int 2 x - 1 d x

Take the constant out:

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

= 2 \cdot \int x - 1 d x

Apply u-substitution

: \int u d u

= 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 = x - 1

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

Simplify

2 \cdot \frac{2}{3} (x - 1)^{\frac{3}{2}} : \frac{4}{3} (x - 1)^{\frac{3}{2}}

= \frac{4}{3} (x - 1)^{\frac{3}{2}}

Add a constant to the solution

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

\int t^{3} e^{- 3 t} d t

\int (3 x + \frac{x}{( x ^{2} + 2 ) ^{\frac{4}{3}}}) d x

f (x) = 3 cos (x)

x \to 0 + lim (3 sin (x) ln (x))

\frac{d}{d x} (x + (x^{6})^{3})
