Practical Example

Suppose you want to verify the trigonometric identity:

Expression 1 (LHS): sin(x)^2 + cos(x)^2
Expression 2 (RHS): 1

Steps:

1. Enter sin(x)^2 + cos(x)^2 in the LHS field.
2. Enter 1 in the RHS field.
3. Click Calculate.

Result: ✅ Identity Holds

The calculator confirms the well-known Pythagorean trigonometric identity, instantly simplifying the verification process.
