    Tan 56 Degrees

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

    What is tan 56°?

    Answer

    tan 56° ≈
    1.4826

    Angle in radians: 56° = 14π/45. The point of the angle is in quadrant I, where tangent is positive.

    ≈ — rounded to 4 decimal places. tan 56° can't be written with square roots: 56° is not a multiple of 3°.

    tan 56° = sin 56° / cos 56° ≈ 1.4826

    xyOP

    P(cos 56°, sin 56°) ≈ (0.5592, 0.8290)

    T(1, tan 56°) ≈ (1, 1.4826) — where line OP meets the line x = 1.

    FAQ

    What is tan 56°?

    tan 56° ≈ 1.4826

    Why does tan 56° 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°. 56° is not, so no such exact form exists; the value is used as a decimal: tan 56° ≈ 1.4826.

    Why does a calculator show −0.6113 for tan 56?

    The calculator is in radian mode (RAD): it takes tan 56 as the tangent of 56 radians, tan 56 rad ≈ −0.6113. Switch it to degrees (DEG): tan 56° ≈ 1.4826. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
