integral from pi/2 to (3pi)/4 of 1

\int_{\frac{π}{2}}^{\frac{3 π}{4}} 1

\frac{π}{4}

Decimal Notation

0.78539 \dots

Solution steps

\int_{\frac{π}{2}}^{\frac{3 π}{4}} 1 d x

Integral of a constant:

\int a d x = a x

= [1 \cdot x]_{\frac{π}{2}}^{\frac{3 π}{4}}

Simplify

= [x]_{\frac{π}{2}}^{\frac{3 π}{4}}

Compute the boundaries:

\frac{π}{4}

= \frac{π}{4}

\int_{0}^{y} c e^{- 2 y} d x

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

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

\int_{0}^{1} π (- ln (x))^{2} d x

\int_{9}^{10} - f (u) d u
