integral of 5xsin(x)

\int 5 x sin (x) d x

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

Solution steps

\int 5 x sin (x) d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 5 \cdot \int x sin (x) d x

Apply Integration By Parts

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

= 5 (- x cos (x) - \int - cos (x) d x)

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

= 5 (- x cos (x) - (- sin (x)))

Simplify

= 5 (- x cos (x) + sin (x))

Add a constant to the solution

= 5 (- x cos (x) + sin (x)) + C

14 x

5 - 2 t

f (x) = e^{l n (c o s (x^{2}))} 2 x + 1

\int_{0}^{4} (16 x^{2} - x^{4}) d x

\int 10 θ sec^{2} (θ) d θ
