    Cot 25 Degrees

    Sin, Cos, Tan, Cot of an Angle

    Angle (°)

    What is cot 25°?

    Answer

    cot 25° ≈
    2.1445

    Angle in radians: 25° = 5π/36. The point of the angle is in quadrant I, where cotangent is positive.

    ≈ — rounded to 4 decimal places. cot 25° can't be written with square roots: 25° is not a multiple of 3°.

    cot 25° = cos 25° / sin 25° ≈ 2.1445

    xyOP

    P(cos 25°, sin 25°) ≈ (0.9063, 0.4226)

    C(cot 25°, 1) ≈ (2.1445, 1) — where line OP meets the line y = 1; C is beyond the drawing, the arrow points to it.

    FAQ

    What is cot 25°?

    cot 25° ≈ 2.1445

    Why does cot 25° 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°. 25° is not, so no such exact form exists; the value is used as a decimal: cot 25° ≈ 2.1445.

    Why does a calculator show −7.4892 for cot 25?

    The calculator is in radian mode (RAD): it takes cot 25 as the cotangent of 25 radians, cot 25 rad ≈ −7.4892. Switch it to degrees (DEG): cot 25° ≈ 2.1445. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
