integral of 2-xcos(x)

\int 2 - x cos (x) d x

2 x - x sin (x) - cos (x) + C

Solution steps

\int 2 - 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 2 d x - \int x cos (x) d x

\int 2 d x = 2 x

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

= 2 x - (x sin (x) + cos (x))

Simplify

= 2 x - x sin (x) - cos (x)

Add a constant to the solution

= 2 x - x sin (x) - cos (x) + C

\int \frac{1}{v ^{2} + 4} d v

\int \frac{3 x ^{2} + 2 ln ( x )}{x ^{3}} d x

\int \frac{- csc ( θ )}{csc ( θ ) - cot ( θ )} d θ

\int sin (9 x) cos (8 x) d x

\int x \cdot sinh (x) d x
