## Question:

Solve the differential equation. (Use C for any needed constant.)

$$4\frac{dy}{d\theta} = \frac {e^y \sin ^2\theta}{y \sec \theta}$$

## Integration using by parts and variable separable methods

To solve the given integral equation we have to use integration by parts method and variable separable method.

**Integration by parts **.

Let **u** and **{eq}v^{\prime}
{/eq}** be two functions in **t** then

{eq}\int u v^{\prime} dt = u v - \int u ^{\prime} v dt + C {/eq}

**Variable separable method**.

If the differential equation is in the form {eq}\frac { dy}{dx } = F(x) \ G(y)
{/eq} Where **F** and **G** are functions in **x** and **y** respectively .

Then we can convert the given d.e in the form {eq}\frac { dy}{G(y) } = F(x) \ dx \\ => \int \frac { dy}{G(y) } = \int F(x) \ dx {/eq}.
