integral of e^{ax}sin(b)x

\int e^{a x} sin (b) x d x

\frac{e ^{a x} ( - 1 + a x )}{a ^{2} csc ( b )} + C

Solution steps

\int e^{a x} sin (b) x d x

Take the constant out:

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

= sin (b) \cdot \int e^{a x} x d x

Apply Integration By Parts

: e^{a x} \frac{1}{a} x - \int e^{a x} \frac{1}{a} d x

= sin (b) (e^{a x} \frac{1}{a} x - \int e^{a x} \frac{1}{a} d x)

\int e^{a x} \frac{1}{a} d x = e^{a x} \frac{1}{a ^{2}}

= sin (b) (e^{a x} \frac{1}{a} x - e^{a x} \frac{1}{a ^{2}})

Simplify

sin (b) (e^{a x} \frac{1}{a} x - e^{a x} \frac{1}{a ^{2}}) : \frac{e ^{a x} ( - 1 + a x )}{a ^{2} csc ( b )}

= \frac{e ^{a x} ( - 1 + a x )}{a ^{2} csc ( b )}

Add a constant to the solution

= \frac{e ^{a x} ( - 1 + a x )}{a ^{2} csc ( b )} + C

\frac{\partial}{\partial y} (y arcsin (x y))

f (x) = 3 - x + x^{2}

\frac{x}{x + 5}

\frac{d}{d x} (- cos (x) + sin (x))

f (x) = (3 x^{2} + 1)^{4}
