integral of xsin(1x)

\int x sin (1 x) d x

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

Solution steps

\int x sin (1 \cdot x) d x

Simplify

= \int x sin (x) d x

Apply Integration By Parts

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

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

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

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

Simplify

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

Add a constant to the solution

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

\int x^{3} e^{x^{4} + 3} d x

\int 6 x + 1 d x

\int \frac{2 x ^{4} + 9 x ^{3} - x}{x ^{3}} d x

\int \frac{x + 1 + tan ( x )}{x} d x

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