Differentiate each of the following from first principle: `x^2sinx`

Explanation

To differentiate the function \( f(x) = x^2 \sin x \) using the first principle of derivatives, we follow these steps:

### Step 1: Define the derivative using the first principle
The derivative \( f'(x) \) is defined as:
\[ f'(x) = \lim_{h \to 0} \frac{f(x + h) - f(x)}{h} \]
