    Angle (°)

    What is sin 50°?

    Answer

    sin 50° ≈
    0.7660

    Angle in radians: 50° = 5π/18. The point of the angle is in quadrant I, where sine is positive.

    ≈ — rounded to 4 decimal places. sin 50° can't be written with square roots: 50° is not a multiple of 3°.

    P(cos 50°, sin 50°) ≈ (0.6428, 0.7660)

    P(cos 50°, sin 50°) ≈ (0.6428, 0.7660)

    Highlighted: the projection on the y-axis — sine, y ≈ 0.7660.

    FAQ

    What is sin 50°?

    sin 50° ≈ 0.7660

    Why does sin 50° 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°. 50° is not, so no such exact form exists; the value is used as a decimal: sin 50° ≈ 0.7660.

    Why does a calculator show −0.2624 for sin 50?

    The calculator is in radian mode (RAD): it takes sin 50 as the sine of 50 radians, sin 50 rad ≈ −0.2624. Switch it to degrees (DEG): sin 50° ≈ 0.7660. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
