integral from 0 to pi/2 of x-sin(x)

\int_{0}^{\frac{π}{2}} x - sin (x) d x

\frac{π ^{2}}{8} - 1

Decimal Notation

0.23370 \dots

Solution steps

\int_{0}^{\frac{π}{2}} x - sin (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

= \int_{0}^{\frac{π}{2}} x d x - \int_{0}^{\frac{π}{2}} sin (x) d x

\int_{0}^{\frac{π}{2}} x d x = \frac{π ^{2}}{8}

\int_{0}^{\frac{π}{2}} sin (x) d x = 1

= \frac{π ^{2}}{8} - 1

\int_{- 1}^{2} \frac{x}{x + 2} d x

\int_{0}^{\frac{x}{2}} sin (2 t) d t

\int_{1}^{5} x x - 1 d x

\int_{0}^{1} \frac{( e ^{x} + 2 )}{e ^{x}} d x

\int_{0}^{3} 2 x - 3 d x
