    Cos 44 Degrees

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

    What is cos 44°?

    Answer

    cos 44° ≈
    0.7193

    Angle in radians: 44° = 11π/45. The point of the angle is in quadrant I, where cosine is positive.

    ≈ — rounded to 4 decimal places. cos 44° can't be written with square roots: 44° is not a multiple of 3°.

    P(cos 44°, sin 44°) ≈ (0.7193, 0.6947)

    xyOP

    P(cos 44°, sin 44°) ≈ (0.7193, 0.6947)

    Highlighted: the projection on the x-axis — cosine, x ≈ 0.7193.

    FAQ

    What is cos 44°?

    cos 44° ≈ 0.7193

    Why does cos 44° 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°. 44° is not, so no such exact form exists; the value is used as a decimal: cos 44° ≈ 0.7193.

    Why does a calculator show 0.9998 for cos 44?

    The calculator is in radian mode (RAD): it takes cos 44 as the cosine of 44 radians, cos 44 rad ≈ 0.9998. Switch it to degrees (DEG): cos 44° ≈ 0.7193. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
