    Cos 41 Degrees

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

    What is cos 41°?

    Answer

    cos 41° ≈
    0.7547

    Angle in radians: 41° = 41π/180. The point of the angle is in quadrant I, where cosine is positive.

    ≈ — rounded to 4 decimal places. cos 41° can't be written with square roots: 41° is not a multiple of 3°.

    P(cos 41°, sin 41°) ≈ (0.7547, 0.6561)

    xyOP

    P(cos 41°, sin 41°) ≈ (0.7547, 0.6561)

    Highlighted: the projection on the x-axis — cosine, x ≈ 0.7547.

    FAQ

    What is cos 41°?

    cos 41° ≈ 0.7547

    Why does cos 41° 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°. 41° is not, so no such exact form exists; the value is used as a decimal: cos 41° ≈ 0.7547.

    Why does a calculator show −0.9873 for cos 41?

    The calculator is in radian mode (RAD): it takes cos 41 as the cosine of 41 radians, cos 41 rad ≈ −0.9873. Switch it to degrees (DEG): cos 41° ≈ 0.7547. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
