    Tan 86 Degrees

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

    What is tan 86°?

    Answer

    tan 86° ≈
    14.3007

    Angle in radians: 86° = 43π/90. The point of the angle is in quadrant I, where tangent is positive.

    ≈ — rounded to 4 decimal places. tan 86° can't be written with square roots: 86° is not a multiple of 3°.

    tan 86° = sin 86° / cos 86° ≈ 14.3007

    xyOP

    P(cos 86°, sin 86°) ≈ (0.0698, 0.9976)

    T(1, tan 86°) ≈ (1, 14.3007) — where line OP meets the line x = 1; T is beyond the drawing, the arrow points to it.

    FAQ

    What is tan 86°?

    tan 86° ≈ 14.3007

    Why does tan 86° 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°. 86° is not, so no such exact form exists; the value is used as a decimal: tan 86° ≈ 14.3007.

    Why does a calculator show 2.4067 for tan 86?

    The calculator is in radian mode (RAD): it takes tan 86 as the tangent of 86 radians, tan 86 rad ≈ 2.4067. Switch it to degrees (DEG): tan 86° ≈ 14.3007. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
