    Angle (°)

    What is cot 65°?

    Answer

    cot 65° ≈
    0.4663

    Angle in radians: 65° = 13π/36. The point of the angle is in quadrant I, where cotangent is positive.

    ≈ — rounded to 4 decimal places. cot 65° can't be written with square roots: 65° is not a multiple of 3°.

    cot 65° = cos 65° / sin 65° ≈ 0.4663

    xyOP

    P(cos 65°, sin 65°) ≈ (0.4226, 0.9063)

    C(cot 65°, 1) ≈ (0.4663, 1) — where line OP meets the line y = 1.

    FAQ

    What is cot 65°?

    cot 65° ≈ 0.4663

    Why does cot 65° 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°. 65° is not, so no such exact form exists; the value is used as a decimal: cot 65° ≈ 0.4663.

    Why does a calculator show −0.6803 for cot 65?

    The calculator is in radian mode (RAD): it takes cot 65 as the cotangent of 65 radians, cot 65 rad ≈ −0.6803. Switch it to degrees (DEG): cot 65° ≈ 0.4663. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
