How to use the inverse variation calculator
Find the value of y in an inverse variation y = k/x given a known pair of values. Enter constant of variation, input x in the fields above; the output y, constant k check are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “inverse variation”, “y varies inversely with x”, “k over x”, “calculate inverse variation”, “find output y”.
Formula
Variables
- k — Constant of variation
- x — Input x
Worked example
With constant of variation = 12, input x = 3, the calculator gives output y ≈ 4; constant k check ≈ 12.
Frequently asked questions
What is the inverse variation calculator used for?
Find the value of y in an inverse variation y = k/x given a known pair of values. It helps with questions such as “inverse variation”, “y varies inversely with x”, “k over x”.
What is the formula for the inverse variation calculation?
Output y = k / x. Constant k check = k. Here k is constant of variation, x is input x.
What inputs do I need for the inverse variation calculator?
You need constant of variation, input x. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the inverse variation calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the inverse variation result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
