    What is cot 355°?

    Answer

    cot 355° ≈
    −11.4301

    Angle in radians: 355° = 71π/36. The point of the angle is in quadrant IV, where cotangent is negative.

    ≈ — rounded to 4 decimal places. cot 355° can't be written with square roots: 355° is not a multiple of 3°.

    cot 355° = cot(360° − 5°) = −cot 5° ≈ −11.4301

    cot 355° = cos 355° / sin 355° ≈ −11.4301

    xyOP

    P(cos 355°, sin 355°) ≈ (0.9962, −0.0872)

    C(cot 355°, 1) ≈ (−11.4301, 1) — where line OP meets the line y = 1, on the extension of the ray beyond O (dashed); C is beyond the drawing, the arrow points to it.

    FAQ

    What is cot 355°?

    cot 355° ≈ −11.4301

    Why does cot 355° 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°. 355° is not, so no such exact form exists; the value is used as a decimal: cot 355° ≈ −11.4301.

    Why does a calculator show 33,173.7088 for cot 355?

    The calculator is in radian mode (RAD): it takes cot 355 as the cotangent of 355 radians, cot 355 rad ≈ 33,173.7088. Switch it to degrees (DEG): cot 355° ≈ −11.4301. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
