integral of zsin(z)

\int z sin (z) d z

- z cos (z) + sin (z) + C

Solution steps

\int z sin (z) d z

Apply Integration By Parts

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

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

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

= - z cos (z) - (- sin (z))

Simplify

= - z cos (z) + sin (z)

Add a constant to the solution

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

\int x^{\frac{5}{3}} x^{\frac{4}{3}} + 9 d x

\int 2 (2 x + 8)^{3} d x

\int \frac{7}{3 x} d x

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

\int - 8 x^{- 1} d x
