integral from-pi/3 to pi/4 of cos(θ)

\int_{- \frac{π}{3}}^{\frac{π}{4}} cos (θ) d θ

\frac{1}{2} + \frac{3}{2}

Decimal Notation

1.57313 \dots

Solution steps

\int_{- \frac{π}{3}}^{\frac{π}{4}} cos (θ) d θ

Use the common integral:

\int cos (θ) d θ = sin (θ)

= [sin (θ)]_{- \frac{π}{3}}^{\frac{π}{4}}

Compute the boundaries:

\frac{1}{2} + \frac{3}{2}

= \frac{1}{2} + \frac{3}{2}

\int_{3}^{\infty} \frac{7}{x ^{2} + 2} d x

\int_{1}^{3} 5 x - x^{2} d x

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

\int_{0}^{2} 9 x e^{- 3 x} d x

\int_{0}^{2} \frac{1}{9 x ^{2} + 36} d x
