    Angle (°)

    What is sin 35°?

    Answer

    sin 35° ≈
    0.5736

    Angle in radians: 35° = 7π/36. The point of the angle is in quadrant I, where sine is positive.

    ≈ — rounded to 4 decimal places. sin 35° can't be written with square roots: 35° is not a multiple of 3°.

    P(cos 35°, sin 35°) ≈ (0.8192, 0.5736)

    P(cos 35°, sin 35°) ≈ (0.8192, 0.5736)

    Highlighted: the projection on the y-axis — sine, y ≈ 0.5736.

    FAQ

    What is sin 35°?

    sin 35° ≈ 0.5736

    Why does sin 35° 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°. 35° is not, so no such exact form exists; the value is used as a decimal: sin 35° ≈ 0.5736.

    Why does a calculator show −0.4282 for sin 35?

    The calculator is in radian mode (RAD): it takes sin 35 as the sine of 35 radians, sin 35 rad ≈ −0.4282. Switch it to degrees (DEG): sin 35° ≈ 0.5736. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
