    What is cot 450°?

    Answer

    cot 450° =
    0

    Angle in radians: 450° = 5π/2. 450° = 360° + 90° — a full turn plus 90°: the point is on the y-axis, (0, 1).

    cot 450° = cot(450° − 360°) = cot 90°

    cot 450° = cos 450° / sin 450° = 0 / 1 = 0

    xyOP

    P(cos 450°, sin 450°) = (0, 1)

    C(cot 450°, 1) = (0, 1) — where line OP meets the line y = 1.

    +1 turn: the drawing shows 90°.

    FAQ

    What is cot 450°?

    cot 450° = 0

    Why is cot 450° equal to 0?

    450° ends at the same point as 90°, (0, 1), and cot = x / y = 0 / 1 = 0.

    Why does a calculator show 1.0686 for cot 450?

    The calculator is in radian mode (RAD): it takes cot 450 as the cotangent of 450 radians, cot 450 rad ≈ 1.0686. Switch it to degrees (DEG): cot 450° = 0. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
