    What is sin 67°?

    Answer

    sin 67° ≈
    0.9205

    Angle in radians: 67° = 67π/180. The point of the angle is in quadrant I, where sine is positive.

    ≈ — rounded to 4 decimal places. sin 67° can't be written with square roots: 67° is not a multiple of 3°.

    P(cos 67°, sin 67°) ≈ (0.3907, 0.9205)

    P(cos 67°, sin 67°) ≈ (0.3907, 0.9205)

    Highlighted: the projection on the y-axis — sine, y ≈ 0.9205.

    FAQ

    What is sin 67°?

    sin 67° ≈ 0.9205

    Why does sin 67° 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°. 67° is not, so no such exact form exists; the value is used as a decimal: sin 67° ≈ 0.9205.

    Why does a calculator show −0.8555 for sin 67?

    The calculator is in radian mode (RAD): it takes sin 67 as the sine of 67 radians, sin 67 rad ≈ −0.8555. Switch it to degrees (DEG): sin 67° ≈ 0.9205. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
