archimedean spiral radius calculator online

Use archimedean spiral radius calculator online for initial radius, radial rate, angle rad. Signed radial rate in distance per radian. Finite floating-point calculation with the displayed domain; large integer counts can lose exact precision.

How to use it

Enter initial radius. Set radial rate, angle rad. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
initial radiusMain input. Zero or positive values. 1
radial rateOption. Signed finite values. 0.5
angle radOption. Signed finite values. 4

Calculation method

radius = initial_radius+radial_rate*angle_rad (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply archimedean spiral radius calculator to the case below, keeping the displayed units and assumptions. Signed radial rate in distance per radian.

Archimedean Spiral Radius Calculator — worked case

Settings: radial rate: 0.5; angle rad: 4

Input:

1

Calculated result for these inputs:

Output:

{
  "radius": 3
}

Choose the right tool

Choose number theory for exact integer relationships, distribution tools for a declared random model, and geometry tools for coordinates. A density is not a probability and a statistical model does not establish a real-world outcome.

Limitations and common mistakes

  • Signed radial rate in distance per radian. Finite floating-point calculation with the displayed domain; large integer counts can lose exact precision.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
