Find out square root of 4.01 using differential .

Explanation

To find the square root of 4.01 using differentials, we can follow these steps:

### Step 1: Define the function
Let \( y = f(x) = \sqrt{x} \). We want to find \( \sqrt{4.01} \).

### Step 2: Identify the point of approximation
We choose \( x = 4 \) because \( \sqrt{4} = 2 \) is a value we can easily calculate. We also define \( \Delta x = 4.01 - 4 = 0.01 \).
