    Cot 70 Degrees

    Sin, Cos, Tan, Cot of an Angle
    Function
    Angle (°)

    What is cot 70°?

    Answer

    cot 70° ≈
    0.3640

    Angle in radians: 70° = 7π/18. The point of the angle is in quadrant I, where cotangent is positive.

    ≈ — rounded to 4 decimal places. cot 70° can't be written with square roots: 70° is not a multiple of 3°.

    cot 70° = cos 70° / sin 70° ≈ 0.3640

    xyOP

    P(cos 70°, sin 70°) ≈ (0.3420, 0.9397)

    C(cot 70°, 1) ≈ (0.3640, 1) — where line OP meets the line y = 1.

    FAQ

    What is cot 70°?

    cot 70° ≈ 0.3640

    Why does cot 70° 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°. 70° is not, so no such exact form exists; the value is used as a decimal: cot 70° ≈ 0.3640.

    Why does a calculator show 0.8184 for cot 70?

    The calculator is in radian mode (RAD): it takes cot 70 as the cotangent of 70 radians, cot 70 rad ≈ 0.8184. Switch it to degrees (DEG): cot 70° ≈ 0.3640. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
