integral from-3 to 4 of cos(x)-3/(x^5)

\int_{- 3}^{4} cos (x) - \frac{3}{x ^{5}} d x

diverges

Solution steps

\int_{- 3}^{4} cos (x) - \frac{3}{x ^{5}} d x

Find undefined (singularity) points:

x = 0

If exist

b, a < b < c, f (b) =

undefined

, \int_{a}^{c} f (x) d x = \int_{a}^{b} f (x) d x + \int_{b}^{c} f (x) d x

= \int_{- 3}^{0} cos (x) - \frac{3}{x ^{5}} d x + \int_{0}^{4} cos (x) - \frac{3}{x ^{5}} d x

\int_{- 3}^{0} cos (x) - \frac{3}{x ^{5}} d x =

diverges

If part of the expression diverges, then entire expression diverges

= diverges

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

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

\int_{100}^{120} - 0.00006 x^{2} + 6 d x

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

\int_{0}^{π} (cos (x) + 4)^{2} d x
