Obtain the differential coefficient of the following:
`log(tanx+secx)`

Explanation

To find the differential coefficient of the function \( y = \log(\tan x + \sec x) \), we will follow these steps:

### Step 1: Define the Function
Let \( y = \log(\tan x + \sec x) \).

### Step 2: Apply the Chain Rule
To differentiate \( y \) with respect to \( x \), we will use the chain rule. According to the chain rule:
\[
