About this calculator
Overview
Local Extrema Calculator provides a focused educational check for local extrema in the vector-calculus library. It evaluates a documented closed-form demo (grad_r2) so students can cross-check the primary output against a hand calculation.
When to use
Use Local Extrema Calculator for coursework drills, lab prep, or design sanity checks when you need local extrema and can validate critical results with a second method.
Formula / method
Method: run the wired calculator path for `local-extrema-calculator` using the labeled fields on this page. Verification identity: ∇(x²+y²) at (1,2)=(2,4). Start with a well-conditioned demo case, confirm the primary output is finite, then compare against the textbook identity for the same inputs.
Worked example
Example: enter the catalog demo inputs for Local Extrema, compute, and confirm the primary result matches the independent closed-form check (grad_r2).
Interpreting results
Interpret the primary output as local extrema under this page’s numerical assumptions. Ill-conditioned inputs can move results substantially; cross-check sensitive work.
Assumptions
- Inputs are compatible with the selected educational demo.
- Numerical behavior for certification uses closed-form method `grad_r2`.
- Floating-point evaluation may introduce small rounding error.
Limitations
- Educational engineering-mathematics tool — not a substitute for certified CAE software.
- Stub-tier pages share family engines; validate critical designs independently.
- Ill-conditioned inputs can magnify error beyond display precision.
Important note
Educational engineering-mathematics tool. Verify critical designs with hand analysis or certified software.
