    Angle (°)

    What is sin 83°?

    Answer

    sin 83° ≈
    0.9925

    Angle in radians: 83° = 83π/180. The point of the angle is in quadrant I, where sine is positive.

    ≈ — rounded to 4 decimal places. sin 83° can't be written with square roots: 83° is not a multiple of 3°.

    P(cos 83°, sin 83°) ≈ (0.1219, 0.9925)

    P(cos 83°, sin 83°) ≈ (0.1219, 0.9925)

    Highlighted: the projection on the y-axis — sine, y ≈ 0.9925.

    FAQ

    What is sin 83°?

    sin 83° ≈ 0.9925

    Why does sin 83° 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°. 83° is not, so no such exact form exists; the value is used as a decimal: sin 83° ≈ 0.9925.

    Why does a calculator show 0.9684 for sin 83?

    The calculator is in radian mode (RAD): it takes sin 83 as the sine of 83 radians, sin 83 rad ≈ 0.9684. Switch it to degrees (DEG): sin 83° ≈ 0.9925. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
