Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Local Truncation Power Law: solve step-size ratio to answer this question: rearrange the local truncation power law relationship and solve for step-size ratio? Enter leading-error ratio and local method order; the calculator shows step-size ratio. For example: step-size ratio=0.5 and local method order=3 produce leading-error ratio=0.125. The answer tells you step-size ratio.
Age 15Explain it to a 15-year-oldConnect it to the formula
In an asymptotic regime, a local truncation term scales as step size raised to the method order. This page isolates step-size ratio and verifies it in the original relationship. The rule is a=c^(1/b). Its input values are leading-error ratio, local method order, and the main result is step-size ratio. For example: step-size ratio=0.5 and local method order=3 produce leading-error ratio=0.125.
CollegeExplain it at college levelState the model precisely
This calculator evaluates the stated local truncation power law: solve step-size ratio relation over the valid real-number domain stated below. The implemented relation is a=c^(1/b), evaluated from leading-error ratio, local method order to produce step-size ratio. In an asymptotic regime, a local truncation term scales as step size raised to the method order. This page isolates step-size ratio and verifies it in the original relationship. Roundoff and higher-order terms can dominate outside that regime.
Inputs and valid domain
- leading-error ratio must be a finite real number.
- local method order must be a finite real number.
Important boundary: Roundoff and higher-order terms can dominate outside that regime.
The formula
a=c^(1/b)
How the calculator works through it
It substitutes leading-error ratio, local method order into the formula and exposes every numerical step above. The main output is step-size ratio, accompanied by Reconstructed leading-error ratio.
Read the result correctly
The step-size ratio is the direct answer to “rearrange the local truncation power law relationship and solve for step-size ratio.” Read it with the units shown beside the inputs; a sign, angle, percentage or rate changes what the number means.
A worked check
step-size ratio=0.5 and local method order=3 produce leading-error ratio=0.125.
Where this model stops being reliable
Roundoff and higher-order terms can dominate outside that regime.
Learn it by changing one value
Begin with the worked example, then change one value while keeping the others fixed. Compare the new result and calculation steps to identify which part of the formula changed.
