integral from 0 to pi/2 of 1

\int_{0}^{\frac{π}{2}} 1 d θ

\frac{π}{2}

Decimal Notation

1.57079 \dots

Solution steps

\int_{0}^{\frac{π}{2}} 1 d θ

Integral of a constant:

\int a d x = a x

= [1 \cdot θ]_{0}^{\frac{π}{2}}

Simplify

= [θ]_{0}^{\frac{π}{2}}

Compute the boundaries:

\frac{π}{2}

= \frac{π}{2}

\frac{d}{d x} (x^{2} + \frac{3456}{x})

\frac{1}{s ( s ^{2} + 81 )}

\frac{d}{d y} (\frac{w ( x + y )}{x y})

\int_{1}^{4} \frac{x ^{2} + 4}{5 x - x ^{2}} d x

\frac{d}{d x} ((- 2 x^{2} + 2 x + 3) (- x^{2} - 3 x - 4))
