    Angle (°)

    What is cot 77°?

    Answer

    cot 77° ≈
    0.2309

    Angle in radians: 77° = 77π/180. The point of the angle is in quadrant I, where cotangent is positive.

    ≈ — rounded to 4 decimal places. cot 77° can't be written with square roots: 77° is not a multiple of 3°.

    cot 77° = cos 77° / sin 77° ≈ 0.2309

    xyOP

    P(cos 77°, sin 77°) ≈ (0.2250, 0.9744)

    C(cot 77°, 1) ≈ (0.2309, 1) — where line OP meets the line y = 1.

    FAQ

    What is cot 77°?

    cot 77° ≈ 0.2309

    Why does cot 77° 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°. 77° is not, so no such exact form exists; the value is used as a decimal: cot 77° ≈ 0.2309.

    Why does a calculator show −0.0310 for cot 77?

    The calculator is in radian mode (RAD): it takes cot 77 as the cotangent of 77 radians, cot 77 rad ≈ −0.0310. Switch it to degrees (DEG): cot 77° ≈ 0.2309. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
