integral of axsin(x)

\int a x sin (x) d x

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

Solution steps

\int a x sin (x) d x

Take the constant out:

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

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

Apply Integration By Parts

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

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

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

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

Simplify

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

Add a constant to the solution

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

\int cosh (7 x) d x

5 x, at x = 16

x \to 1 lim (x^{2} + 4 x)

x \to 3 lim ([8 + 4 (- 10)])

\int_{- 1}^{4} \frac{1}{∣ x ∣} d x
