Cos 1 Degree: Cosine of 1° on the Unit Circle

What is cos 1°?

Answer

cos 1° ≈

0.9998

Angle in radians: 1° = π/180. The point of the angle is in quadrant I, where cosine is positive.

≈ — rounded to 4 decimal places. cos 1° can't be written with square roots: 1° is not a multiple of 3°.

P(cos 1°, sin 1°) ≈ (0.9998, 0.0175)

Highlighted: the projection on the x-axis — cosine, x ≈ 0.9998.
