    Angle (°)

    What is cot 145°?

    Answer

    cot 145° ≈
    −1.4281

    Angle in radians: 145° = 29π/36. The point of the angle is in quadrant II, where cotangent is negative.

    ≈ — rounded to 4 decimal places. cot 145° can't be written with square roots: 145° is not a multiple of 3°.

    cot 145° = cot(180° − 35°) = −cot 35° ≈ −1.4281

    cot 145° = cos 145° / sin 145° ≈ −1.4281

    xyOP

    P(cos 145°, sin 145°) ≈ (−0.8192, 0.5736)

    C(cot 145°, 1) ≈ (−1.4281, 1) — where line OP meets the line y = 1.

    FAQ

    What is cot 145°?

    cot 145° ≈ −1.4281

    Why does cot 145° 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°. 145° is not, so no such exact form exists; the value is used as a decimal: cot 145° ≈ −1.4281.

    Why does a calculator show 1.8896 for cot 145?

    The calculator is in radian mode (RAD): it takes cot 145 as the cotangent of 145 radians, cot 145 rad ≈ 1.8896. Switch it to degrees (DEG): cot 145° ≈ −1.4281. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
