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

\int_{- \frac{π}{2}}^{\frac{π}{2}} (cos (x)) d x

2

Solution steps

\int_{- \frac{π}{2}}^{\frac{π}{2}} cos (x) d x

Use the common integral:

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

= [sin (x)]_{- \frac{π}{2}}^{\frac{π}{2}}

Compute the boundaries:

2

= 2

\int_{0}^{1} (2 x^{4} - 3 x^{2} + 5) d x

\int_{1}^{2} \frac{5 - 6 x}{x ^{3}} d x

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

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

\int_{1}^{e} \frac{8 ln ( x )}{x} d x
