integral of (xsin(x)-cos(x))

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

- x cos (x) + C

Solution steps

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

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

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

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

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

= - x cos (x) + sin (x) - sin (x)

Simplify

= - x cos (x)

Add a constant to the solution

= - x cos (x) + C

\int \frac{x ^{3} - x ^{2}}{x ^{2} - 7 x + 10} d x

\int e^{2 x} sin (x) cos (x) d x

\int \frac{cos ^{2} ( x )}{sin ^{5} ( x )} d x

\int 2^{x - 3} d x

\int \frac{1}{x} \cdot e^{x} d x
