integral from-pi/4 to pi/4 of 1

\int_{- \frac{π}{4}}^{\frac{π}{4}} 1

\frac{π}{2}

Decimal

1.57079 \dots

Solution steps

\int_{- \frac{π}{4}}^{\frac{π}{4}} 1 d x

Integral of a constant:

\int a d x = a x

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

Simplify

= [x]_{- \frac{π}{4}}^{\frac{π}{4}}

Compute the boundaries:

\frac{π}{2}

= \frac{π}{2}

\frac{d}{d x} (A (2 e^{- x} x - e^{- x} x^{2}))

\int_{1}^{e^{3}} x^{2} ln (x) d x

x \to 5 lim (123)

\frac{d}{d x} (\frac{1}{3} x^{\frac{1}{2}} - x^{\frac{3}{2}})

(- 1 x y^{2} + 2 y) d x + (- 1 x^{2} y + 2 x) d y = 0
