integral of 3x^4+x^2+2

\int 3 x^{4} + x^{2} + 2 d x

\frac{3 x ^{5}}{5} + \frac{x ^{3}}{3} + 2 x + C

Solution steps

\int 3 x^{4} + x^{2} + 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 3 x^{4} d x + \int x^{2} d x + \int 2 d x

\int 3 x^{4} d x = \frac{3 x ^{5}}{5}

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

\int 2 d x = 2 x

= \frac{3 x ^{5}}{5} + \frac{x ^{3}}{3} + 2 x

Add a constant to the solution

= \frac{3 x ^{5}}{5} + \frac{x ^{3}}{3} + 2 x + C

\int 5 x^{2} + x d x

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

\int \frac{x ^{5} - x}{x ^{2} + 1} d x

\int cos (10 x + 2) cos (8 x - 2) d x
