integral from pi/2 to pi of cos(x)

\int_{\frac{π}{2}}^{π} cos (x) d x

- 1

Solution steps

\int_{\frac{π}{2}}^{π} cos (x) d x

Use the common integral:

\int cos (x) d x = sin (x)

= [sin (x)]_{\frac{π}{2}}^{π}

Compute the boundaries:

- 1

= - 1

\int \frac{1}{e ^{x} + 4 e ^{- x}} d x

\int_{1}^{3} 2 π x (- x^{2} + 4 x - 3) d x

y = x^{\frac{3}{2}} (x + c e^{x})

\int 10 - (14 - 2 (16 - 2 x)^{\frac{1}{2}}) d x

\int 8 x^{9} e^{- x^{5}} d x
