    Tan 43 Degrees

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

    What is tan 43°?

    Answer

    tan 43° ≈
    0.9325

    Angle in radians: 43° = 43π/180. The point of the angle is in quadrant I, where tangent is positive.

    ≈ — rounded to 4 decimal places. tan 43° can't be written with square roots: 43° is not a multiple of 3°.

    tan 43° = sin 43° / cos 43° ≈ 0.9325

    xyOP

    P(cos 43°, sin 43°) ≈ (0.7314, 0.6820)

    T(1, tan 43°) ≈ (1, 0.9325) — where line OP meets the line x = 1.

    FAQ

    What is tan 43°?

    tan 43° ≈ 0.9325

    Why does tan 43° 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°. 43° is not, so no such exact form exists; the value is used as a decimal: tan 43° ≈ 0.9325.

    Why does a calculator show −1.4984 for tan 43?

    The calculator is in radian mode (RAD): it takes tan 43 as the tangent of 43 radians, tan 43 rad ≈ −1.4984. Switch it to degrees (DEG): tan 43° ≈ 0.9325. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
