integral from 5 to 10 of sqrt(100-x^2)

\int_{5}^{10} 100 - x^{2} d x

50 (\frac{π}{3} - \frac{3}{4})

Decimal Notation

30.70924 \dots

Solution steps

\int_{5}^{10} 100 - x^{2} d x

Apply Trigonometric Substitution

: \int_{\frac{π}{6}}^{\frac{π}{2}} 100 cos^{2} (u) d u

= \int_{\frac{π}{6}}^{\frac{π}{2}} 100 cos^{2} (u) d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 100 \cdot \int_{\frac{π}{6}}^{\frac{π}{2}} cos^{2} (u) d u

Rewrite using trig identities

= 100 \cdot \int_{\frac{π}{6}}^{\frac{π}{2}} \frac{1 + cos ( 2 u )}{2} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 100 \cdot \frac{1}{2} \cdot \int_{\frac{π}{6}}^{\frac{π}{2}} 1 + cos (2 u) d u

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= 100 \cdot \frac{1}{2} (\int_{\frac{π}{6}}^{\frac{π}{2}} 1 d u + \int_{\frac{π}{6}}^{\frac{π}{2}} cos (2 u) d u)

\int_{\frac{π}{6}}^{\frac{π}{2}} 1 d u = \frac{π}{3}

\int_{\frac{π}{6}}^{\frac{π}{2}} cos (2 u) d u = - \frac{3}{4}

= 100 \cdot \frac{1}{2} (\frac{π}{3} - \frac{3}{4})

Simplify

100 \cdot \frac{1}{2} (\frac{π}{3} - \frac{3}{4}) : 50 (\frac{π}{3} - \frac{3}{4})

= 50 (\frac{π}{3} - \frac{3}{4})

\frac{d}{d x} (π^{3})

\frac{1}{8} x^{2} - 7 x + 16

\frac{\partial}{\partial x} (6 x e^{x y})

\int sin (x) co x d x

\int (5 x + 4 sin (x)) d x
