integral from 0 to pi of sin^2(5x)

\int_{0}^{π} sin^{2} (5 x) d x

\frac{π}{2}

Decimal

1.57079 \dots

Solution steps

\int_{0}^{π} sin^{2} (5 x) d x

Rewrite using trig identities

= \int_{0}^{π} \frac{1}{2} (1 - cos (10 x)) d x

Take the constant out:

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

= \frac{1}{2} \cdot \int_{0}^{π} 1 - cos (10 x) 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

= \frac{1}{2} (\int_{0}^{π} 1 d x - \int_{0}^{π} cos (10 x) d x)

\int_{0}^{π} 1 d x = π

\int_{0}^{π} cos (10 x) d x = 0

= \frac{1}{2} (π - 0)

Simplify

\frac{1}{2} (π - 0) : \frac{π}{2}

= \frac{π}{2}

\frac{d y}{d x} + 2 y = 4

(5, - 3), (- 3, 6)

(\frac{1}{x})^{^{'}}

\frac{\partial}{\partial x} (2 x^{2} y + sin (x^{2}))

x^{2} (1 - 7 x)
