What is sin 37°?

Answer

sin 37° ≈
0.6018

Angle in radians: 37° = 37π/180. The point of the angle is in quadrant I, where sine is positive.

≈ — rounded to 4 decimal places. sin 37° can't be written with square roots: 37° is not a multiple of 3°.

P(cos 37°, sin 37°) ≈ (0.7986, 0.6018)

FAQ

What is sin 37°?

sin 37° ≈ 0.6018

Why does sin 37° 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°. 37° is not, so no such exact form exists; the value is used as a decimal: sin 37° ≈ 0.6018.

Why does a calculator show −0.6435 for sin 37?

The calculator is in radian mode (RAD): it takes sin 37 as the sine of 37 radians, sin 37 rad ≈ −0.6435. Switch it to degrees (DEG): sin 37° ≈ 0.6018. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
