Find the value of tan A, if area of `Delta ABC is a^(2) -(b-c)^(2).`

Explanation

To find the value of \( \tan A \) given that the area of triangle \( ABC \) is \( a^2 - (b - c)^2 \), we can follow these steps:

### Step 1: Express the Area of the Triangle
The area \( \Delta \) of triangle \( ABC \) is given by:
\[ \Delta = a^2 - (b - c)^2 \]
We can rewrite this expression using the difference of squares:
