    Angle (°)

    What is cot 64°?

    Answer

    cot 64° ≈
    0.4877

    Angle in radians: 64° = 16π/45. The point of the angle is in quadrant I, where cotangent is positive.

    ≈ — rounded to 4 decimal places. cot 64° can't be written with square roots: 64° is not a multiple of 3°.

    cot 64° = cos 64° / sin 64° ≈ 0.4877

    xyOP

    P(cos 64°, sin 64°) ≈ (0.4384, 0.8988)

    C(cot 64°, 1) ≈ (0.4877, 1) — where line OP meets the line y = 1.

    FAQ

    What is cot 64°?

    cot 64° ≈ 0.4877

    Why does cot 64° 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°. 64° is not, so no such exact form exists; the value is used as a decimal: cot 64° ≈ 0.4877.

    Why does a calculator show 0.4259 for cot 64?

    The calculator is in radian mode (RAD): it takes cot 64 as the cotangent of 64 radians, cot 64 rad ≈ 0.4259. Switch it to degrees (DEG): cot 64° ≈ 0.4877. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
