integral from 0 to 1 of (x+5sqrt(1-x^2))

\int_{0}^{1} (x + 5 1 - x^{2}) d x

\frac{1}{2} + \frac{5 π}{4}

Decimal

4.42699 \dots

Solution steps

\int_{0}^{1} x + 5 1 - x^{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_{0}^{1} x d x + \int_{0}^{1} 5 1 - x^{2} d x

\int_{0}^{1} x d x = \frac{1}{2}

\int_{0}^{1} 5 1 - x^{2} d x = \frac{5 π}{4}

= \frac{1}{2} + \frac{5 π}{4}
