integral of e^{10x}sin(x)

\int e^{10 x} sin (x) d x

- \frac{e ^{10 x} cos ( x )}{101} + \frac{10 e ^{10 x} sin ( x )}{101} + C

Solution steps

\int e^{10 x} sin (x) d x

Apply Integration By Parts

: - e^{10 x} cos (x) - \int - 10 e^{10 x} cos (x) d x

= - e^{10 x} cos (x) - \int - 10 e^{10 x} cos (x) d x

Take the constant out:

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

= - e^{10 x} cos (x) - (- 10 \cdot \int e^{10 x} cos (x) d x)

Apply Integration By Parts

: e^{10 x} sin (x) - \int e^{10 x} \cdot 10 sin (x) d x

= - e^{10 x} cos (x) - (- 10 (e^{10 x} sin (x) - \int e^{10 x} \cdot 10 sin (x) d x))

Take the constant out:

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

= - e^{10 x} cos (x) - (- 10 (e^{10 x} sin (x) - 10 \cdot \int e^{10 x} sin (x) d x))

Therefore

\int e^{10 x} sin (x) d x = - e^{10 x} cos (x) - (- 10 (e^{10 x} sin (x) - 10 \cdot \int e^{10 x} sin (x) d x))

Isolate

\int e^{10 x} sin (x) d x

= - \frac{e ^{10 x} cos ( x )}{101} + \frac{10 e ^{10 x} sin ( x )}{101}

Add a constant to the solution

= - \frac{e ^{10 x} cos ( x )}{101} + \frac{10 e ^{10 x} sin ( x )}{101} + C

\int (y e^{x y} - \frac{1}{y}) d x

\int - 2 tan (2 x) sec (2 x) d x

\int \frac{1 - x}{2 - x} d x

\int \frac{5 t ^{4}}{t ^{5} + 2} d t

\int 25 + 16 x^{2} d x
