integral of sqrt(x)-x+2

\int x - x + 2 d x

\frac{2}{3} x^{\frac{3}{2}} - \frac{x ^{2}}{2} + 2 x + C

Solution steps

\int x - x + 2 d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int x d x - \int x d x + \int 2 d x

\int x d x = \frac{2}{3} x^{\frac{3}{2}}

\int x d x = \frac{x ^{2}}{2}

\int 2 d x = 2 x

= \frac{2}{3} x^{\frac{3}{2}} - \frac{x ^{2}}{2} + 2 x

Add a constant to the solution

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

\frac{\partial}{\partial y} (12 y - 5 x cos (y))

3 x + 2

\int cos^{4} (x s i) n^{2} x d x

\int \frac{x}{( 4 x ^{2} + 3 ) ^{6}} d x

e^{- t} (t^{2} + 1)
