    Cos 46 Degrees

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

    What is cos 46°?

    Answer

    cos 46° ≈
    0.6947

    Angle in radians: 46° = 23π/90. The point of the angle is in quadrant I, where cosine is positive.

    ≈ — rounded to 4 decimal places. cos 46° can't be written with square roots: 46° is not a multiple of 3°.

    P(cos 46°, sin 46°) ≈ (0.6947, 0.7193)

    P(cos 46°, sin 46°) ≈ (0.6947, 0.7193)

    Highlighted: the projection on the x-axis — cosine, x ≈ 0.6947.

    FAQ

    What is cos 46°?

    cos 46° ≈ 0.6947

    Why does cos 46° 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°. 46° is not, so no such exact form exists; the value is used as a decimal: cos 46° ≈ 0.6947.

    Why does a calculator show −0.4322 for cos 46?

    The calculator is in radian mode (RAD): it takes cos 46 as the cosine of 46 radians, cos 46 rad ≈ −0.4322. Switch it to degrees (DEG): cos 46° ≈ 0.6947. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
