What is sin 29°?

Answer

sin 29° ≈
0.4848

Angle in radians: 29° = 29π/180. The point of the angle is in quadrant I, where sine is positive.

≈ — rounded to 4 decimal places. sin 29° can't be written with square roots: 29° is not a multiple of 3°.

P(cos 29°, sin 29°) ≈ (0.8746, 0.4848)

FAQ

What is sin 29°?

sin 29° ≈ 0.4848

Why does sin 29° 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°. 29° is not, so no such exact form exists; the value is used as a decimal: sin 29° ≈ 0.4848.

Why does a calculator show −0.6636 for sin 29?

The calculator is in radian mode (RAD): it takes sin 29 as the sine of 29 radians, sin 29 rad ≈ −0.6636. Switch it to degrees (DEG): sin 29° ≈ 0.4848. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
