integral of 5xcos(x)

\int 5 x cos (x) d x

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

Solution steps

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

Apply Integration By Parts

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

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

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

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

Simplify

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

Add a constant to the solution

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

\frac{( s + 2 )}{( s ^{2} + 3 s + 1 )}

\int \frac{5 x ^{3}}{( 5 - 3 x ^{4} ) ^{8}} d x

\frac{\partial}{\partial x} (sin (x^{2} + y^{2}))

x \to 2 + lim (3 + ∣ 2 x - 4 ∣)

\frac{d}{d y} (cos (x) - y)
