## Question:

Evaluate the integral. (Use {eq}C{/eq} for the constant of integration.)

{eq}\displaystyle \int e^{4\theta} \:\text{sin}\:(\text{5}\theta) \:d\theta{/eq}

## Integration by Parts method:

In mathematics, finding the integration or antiderivative of a function is the inverse process of differentiation. The by parts method of the integration is a special method that comes in the picture when two functions (multiple of two functions) come together in the integrand.

According to the integration by parts method:

{eq}\int {f(t)g(t)} dt = f(t)\int {g(t)dt} - \int {\left( {\dfrac{d}{{dt}}f(t)\int {g(t)dt} } \right)} dt {/eq}
