    Angle (°)

    What is sin 11°?

    Answer

    sin 11° ≈
    0.1908

    Angle in radians: 11° = 11π/180. The point of the angle is in quadrant I, where sine is positive.

    ≈ — rounded to 4 decimal places. sin 11° can't be written with square roots: 11° is not a multiple of 3°.

    P(cos 11°, sin 11°) ≈ (0.9816, 0.1908)

    P(cos 11°, sin 11°) ≈ (0.9816, 0.1908)

    Highlighted: the projection on the y-axis — sine, y ≈ 0.1908.

    FAQ

    What is sin 11°?

    sin 11° ≈ 0.1908

    Why does sin 11° 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°. 11° is not, so no such exact form exists; the value is used as a decimal: sin 11° ≈ 0.1908.

    Why does a calculator show −1.0000 for sin 11?

    The calculator is in radian mode (RAD): it takes sin 11 as the sine of 11 radians, sin 11 rad ≈ −1.0000. Switch it to degrees (DEG): sin 11° ≈ 0.1908. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
