Work out coterminal angle instantly with clear inputs, formula shown and shareable results.
Coterminal angles share the same terminal arm, so they differ by whole revolutions: θ + 360°k for any integer k. Reducing modulo 360° gives the least positive representative.
Coterminal angles
θ' = θ + 360°·k (or θ + 2πk radians)
45 + 720 = 765°, which has the same sine, cosine and tangent as 45°.
Yes. They differ by exactly 360°, so they end on the same ray.
