integral from-1 to 4 of (3x^4-4x^3-x-4)

\int_{- 1}^{4} (3 x^{4} - 4 x^{3} - x - 4) d x

\frac{665}{2}

Decimal

332.5

Solution steps

\int_{- 1}^{4} 3 x^{4} - 4 x^{3} - x - 4 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_{- 1}^{4} 3 x^{4} d x - \int_{- 1}^{4} 4 x^{3} d x - \int_{- 1}^{4} x d x - \int_{- 1}^{4} 4 d x

\int_{- 1}^{4} 3 x^{4} d x = 615

\int_{- 1}^{4} 4 x^{3} d x = 255

\int_{- 1}^{4} x d x = \frac{15}{2}

\int_{- 1}^{4} 4 d x = 20

= 615 - 255 - \frac{15}{2} - 20

Simplify

615 - 255 - \frac{15}{2} - 20 : \frac{665}{2}

= \frac{665}{2}

\int_{0}^{2} (6 x - 6) (8 x^{2} + 2) d x

\int_{1}^{12} \frac{4}{x ^{2}} ln (x) d x

\int_{- 7}^{8} x d x

\int_{0}^{1} e^{5 x} - e^{4 x} d x

\int_{0}^{\infty} tan (x) d x
