integral of (x^4+2x^3-5x+9)

\int (x^{4} + 2 x^{3} - 5 x + 9) d x

\frac{x ^{5}}{5} + \frac{x ^{4}}{2} - \frac{5 x ^{2}}{2} + 9 x + C

Solution steps

\int x^{4} + 2 x^{3} - 5 x + 9 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^{4} d x + \int 2 x^{3} d x - \int 5 x d x + \int 9 d x

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

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

\int 5 x d x = \frac{5 x ^{2}}{2}

\int 9 d x = 9 x

= \frac{x ^{5}}{5} + \frac{x ^{4}}{2} - \frac{5 x ^{2}}{2} + 9 x

Add a constant to the solution

= \frac{x ^{5}}{5} + \frac{x ^{4}}{2} - \frac{5 x ^{2}}{2} + 9 x + C

x \to o lim (e^{x})

arcsin (8 x) + arccos (8 x)

x \to + 0 lim (\frac{sin ( 5 x )}{5})

n = 1 \sum \infty \frac{x ^{n}}{n 5 ^{n}}

\int 27 tan^{3} (x) sec (x) d x
