    Cos 29 Degrees

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

    What is cos 29°?

    Answer

    cos 29° ≈
    0.8746

    Angle in radians: 29° = 29π/180. The point of the angle is in quadrant I, where cosine is positive.

    ≈ — rounded to 4 decimal places. cos 29° can't be written with square roots: 29° is not a multiple of 3°.

    P(cos 29°, sin 29°) ≈ (0.8746, 0.4848)

    P(cos 29°, sin 29°) ≈ (0.8746, 0.4848)

    Highlighted: the projection on the x-axis — cosine, x ≈ 0.8746.

    FAQ

    What is cos 29°?

    cos 29° ≈ 0.8746

    Why does cos 29° 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°. 29° is not, so no such exact form exists; the value is used as a decimal: cos 29° ≈ 0.8746.

    Why does a calculator show −0.7481 for cos 29?

    The calculator is in radian mode (RAD): it takes cos 29 as the cosine of 29 radians, cos 29 rad ≈ −0.7481. Switch it to degrees (DEG): cos 29° ≈ 0.8746. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
