    Angle (°)

    What is sin 59°?

    Answer

    sin 59° ≈
    0.8572

    Angle in radians: 59° = 59π/180. The point of the angle is in quadrant I, where sine is positive.

    ≈ — rounded to 4 decimal places. sin 59° can't be written with square roots: 59° is not a multiple of 3°.

    P(cos 59°, sin 59°) ≈ (0.5150, 0.8572)

    FAQ

    What is sin 59°?

    sin 59° ≈ 0.8572

    Why does sin 59° 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°. 59° is not, so no such exact form exists; the value is used as a decimal: sin 59° ≈ 0.8572.

    Why does a calculator show 0.6367 for sin 59?

    The calculator is in radian mode (RAD): it takes sin 59 as the sine of 59 radians, sin 59 rad ≈ 0.6367. Switch it to degrees (DEG): sin 59° ≈ 0.8572. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
