Problem

Find the coordinates on the unit circle at 240°

Answer

(-0.5, -0.866)

Worked solution

(cos 240°, sin 240°) = (-0.5, -0.866)

Notes

  • · Change the problem number to generate a new random problem.
  • · Try to solve it yourself before checking the worked solution.

Unit Circle Practice Generator — How It Works

Unit Circle Practice Generator — How It Works

Practicing the same type of problem repeatedly is one of the best ways to build fluency. The Unit Circle Practice Generator generates a fresh random problem for coordinates on the unit circle, with a worked solution so you can check your work. Try the Unit Circle Practice Generator — instant results, no sign-up.

How it works

  1. The tool generates a problem based on a “problem number” — change the number to get a new (but reproducible) problem.
  2. Try to solve the problem yourself.
  3. Reveal the answer and worked solution to check your work.

The underlying formula

(cos θ, sin θ) for a standard angle θ

Tips

  • Work through several problem numbers in a row for repeated practice.
  • If you get a problem wrong, re-read the worked solution step by step before moving to the next one.
  • This tool is a starting point — for harder problems, try larger numbers or combine it with other practice generators in Math & Education.

FAQ
