What is sin 32°?

Answer

sin 32° ≈
0.5299

Angle in radians: 32° = 8π/45. The point of the angle is in quadrant I, where sine is positive.

≈ — rounded to 4 decimal places. sin 32° can't be written with square roots: 32° is not a multiple of 3°.

P(cos 32°, sin 32°) ≈ (0.8480, 0.5299)

FAQ

What is sin 32°?

sin 32° ≈ 0.5299

Why does sin 32° have no exact value?

A trigonometric value of a whole number of degrees can be written with square roots only when the angle is a multiple of 3°. 32° is not, so no such exact form exists; the value is used as a decimal: sin 32° ≈ 0.5299.

Why does a calculator show 0.5514 for sin 32?

The calculator is in radian mode (RAD): it takes sin 32 as the sine of 32 radians, sin 32 rad ≈ 0.5514. Switch it to degrees (DEG): sin 32° ≈ 0.5299. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
