    Tan 34 Degrees

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

    What is tan 34°?

    Answer

    tan 34° ≈
    0.6745

    Angle in radians: 34° = 17π/90. The point of the angle is in quadrant I, where tangent is positive.

    ≈ — rounded to 4 decimal places. tan 34° can't be written with square roots: 34° is not a multiple of 3°.

    tan 34° = sin 34° / cos 34° ≈ 0.6745

    xyOP

    P(cos 34°, sin 34°) ≈ (0.8290, 0.5592)

    T(1, tan 34°) ≈ (1, 0.6745) — where line OP meets the line x = 1.

    FAQ

    What is tan 34°?

    tan 34° ≈ 0.6745

    Why does tan 34° 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°. 34° is not, so no such exact form exists; the value is used as a decimal: tan 34° ≈ 0.6745.

    Why does a calculator show −0.6235 for tan 34?

    The calculator is in radian mode (RAD): it takes tan 34 as the tangent of 34 radians, tan 34 rad ≈ −0.6235. Switch it to degrees (DEG): tan 34° ≈ 0.6745. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
