    Cos 37 Degrees

    Sin, Cos, Tan, Cot of an Angle
    Function
    Angle (°)

    What is cos 37°?

    Answer

    cos 37° ≈
    0.7986

    Angle in radians: 37° = 37π/180. The point of the angle is in quadrant I, where cosine is positive.

    ≈ — rounded to 4 decimal places. cos 37° can't be written with square roots: 37° is not a multiple of 3°.

    P(cos 37°, sin 37°) ≈ (0.7986, 0.6018)

    xyOP

    P(cos 37°, sin 37°) ≈ (0.7986, 0.6018)

    Highlighted: the projection on the x-axis — cosine, x ≈ 0.7986.

    FAQ

    What is cos 37°?

    cos 37° ≈ 0.7986

    Why does cos 37° 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°. 37° is not, so no such exact form exists; the value is used as a decimal: cos 37° ≈ 0.7986.

    Why does a calculator show 0.7654 for cos 37?

    The calculator is in radian mode (RAD): it takes cos 37 as the cosine of 37 radians, cos 37 rad ≈ 0.7654. Switch it to degrees (DEG): cos 37° ≈ 0.7986. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
