integral of (7x^4+4sqrt(x)+1/(x^3))

\int (7 x^{4} + 4 x + \frac{1}{x ^{3}}) d x

\frac{7 x ^{5}}{5} + \frac{8}{3} x^{\frac{3}{2}} - \frac{1}{2 x ^{2}} + C

Solution steps

\int 7 x^{4} + 4 x + \frac{1}{x ^{3}} 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 7 x^{4} d x + \int 4 x d x + \int \frac{1}{x ^{3}} d x

\int 7 x^{4} d x = \frac{7 x ^{5}}{5}

\int 4 x d x = \frac{8}{3} x^{\frac{3}{2}}

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

= \frac{7 x ^{5}}{5} + \frac{8}{3} x^{\frac{3}{2}} - \frac{1}{2 x ^{2}}

Add a constant to the solution

= \frac{7 x ^{5}}{5} + \frac{8}{3} x^{\frac{3}{2}} - \frac{1}{2 x ^{2}} + C

\int 8 x sin (2 x) d x

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

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

\int \frac{e ^{3 x}}{e ^{3 x} - 6} d x

\int \frac{2 x}{x ^{2} + y ^{2}} d x
