    What is sin 22°?

    Answer

    sin 22° ≈
    0.3746

    Angle in radians: 22° = 11π/90. The point of the angle is in quadrant I, where sine is positive.

    ≈ — rounded to 4 decimal places. sin 22° can't be written with square roots: 22° is not a multiple of 3°.

    P(cos 22°, sin 22°) ≈ (0.9272, 0.3746)

    FAQ

    What is sin 22°?

    sin 22° ≈ 0.3746

    Why does sin 22° 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°. 22° is not, so no such exact form exists; the value is used as a decimal: sin 22° ≈ 0.3746.

    Why does a calculator show −0.0089 for sin 22?

    The calculator is in radian mode (RAD): it takes sin 22 as the sine of 22 radians, sin 22 rad ≈ −0.0089. Switch it to degrees (DEG): sin 22° ≈ 0.3746. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
