Integrate the following :
`int(1)/(1+sin theta)d theta`

Explanation

To solve the integral \( \int \frac{1}{1 + \sin \theta} \, d\theta \), we can follow these steps:

### Step 1: Rationalize the Denominator
We will multiply the numerator and denominator by \( 1 - \sin \theta \):
\[ \int \frac{1}{1 + \sin \theta} \, d\theta = \int \frac{1 - \sin \theta}{(1 + \sin \theta)(1 - \sin \theta)} \, d\theta \]
