    Tan 0 Degrees

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

    What is tan 0°?

    Answer

    tan 0° =
    0

    Angle in radians: 0° = 0. The point of the angle is on the x-axis: (1, 0).

    tan 0° = sin 0° / cos 0° = 0 / 1 = 0

    xyOP

    P(cos 0°, sin 0°) = (1, 0)

    T(1, tan 0°) = (1, 0) — where line OP meets the line x = 1.
