Practical Example

Imagine you want to find the partial derivatives of the function: f(x,y)=x2⋅y+sin⁡(y)f(x, y) = x^2 \cdot y + \sin(y)f(x,y)=x2⋅y+sin(y)

1. Enter the function in the calculator: x^2*y + sin(y).
2. Input the variables: x, y.
3. Click Calculate.

The tool will provide:

• ∂f/∂x ≈ calculated numerically
