    Angle (°)

    What is sin 34°?

    Answer

    sin 34° ≈
    0.5592

    Angle in radians: 34° = 17π/90. The point of the angle is in quadrant I, where sine is positive.

    ≈ — rounded to 4 decimal places. sin 34° can't be written with square roots: 34° is not a multiple of 3°.

    P(cos 34°, sin 34°) ≈ (0.8290, 0.5592)

    P(cos 34°, sin 34°) ≈ (0.8290, 0.5592)

    Highlighted: the projection on the y-axis — sine, y ≈ 0.5592.

    FAQ

    What is sin 34°?

    sin 34° ≈ 0.5592

    Why does sin 34° 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°. 34° is not, so no such exact form exists; the value is used as a decimal: sin 34° ≈ 0.5592.

    Why does a calculator show 0.5291 for sin 34?

    The calculator is in radian mode (RAD): it takes sin 34 as the sine of 34 radians, sin 34 rad ≈ 0.5291. Switch it to degrees (DEG): sin 34° ≈ 0.5592. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
