integral from 1 to 2 of (1+x^3)

Solution

\int_{1}^{2} (1 + x^{3}) d x

Solution

\frac{19}{4}

+1

Decimal

4.75

Solution steps

\int_{1}^{2} 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_{1}^{2} 1 d x + \int_{1}^{2} x^{3} d x

\int_{1}^{2} 1 d x = 1

\int_{1}^{2} x^{3} d x = \frac{15}{4}

= 1 + \frac{15}{4}

Simplify

1 + \frac{15}{4} : \frac{19}{4}

= \frac{19}{4}
