What this calculator teaches
The gradient points in the direction of steepest increase. For a multivariable function, each component is a partial derivative.
This page is written as an educational calculator: it gives a result, shows the governing formula, and explains how to interpret the answer instead of returning only a number.

Common Mistakes to Avoid
Check conditions such as units, dimensions, convergence, step size, matrix singularity, or stability before using the result.
Keep extra digits during intermediate work and round only the final answer.
Always connect each variable to the real quantity it represents in your problem.
