differentiate with respect to x to the given function`(x^(2)cos(pi/4))/(sinx)`

Explanation

To differentiate the function \( y = \frac{x^2 \cos(\frac{\pi}{4})}{\sin x} \) with respect to \( x \), we can follow these steps:

### Step 1: Simplify the Function
First, we can simplify the function by substituting the value of \( \cos(\frac{\pi}{4}) \):
\[ \cos\left(\frac{\pi}{4}\right) = \frac{1}{\sqrt{2}} \]
Thus, the function becomes:
