Find the general solution of the differential equations `e^xtanydx+(1-e^x)sec^2ydy=0`

Explanation

To solve the differential equation \( e^x \tan y \, dx + (1 - e^x) \sec^2 y \, dy = 0 \), we will follow these steps:

### Step 1: Rearranging the Equation
We start by rearranging the equation to separate the variables \( x \) and \( y \):
\[ e^x \tan y \, dx = - (1 - e^x) \sec^2 y \, dy \]
This can be rewritten as:
