    Tan 49 Degrees

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

    What is tan 49°?

    Answer

    tan 49° ≈
    1.1504

    Angle in radians: 49° = 49π/180. The point of the angle is in quadrant I, where tangent is positive.

    ≈ — rounded to 4 decimal places. tan 49° can't be written with square roots: 49° is not a multiple of 3°.

    tan 49° = sin 49° / cos 49° ≈ 1.1504

    xyOP

    P(cos 49°, sin 49°) ≈ (0.6561, 0.7547)

    T(1, tan 49°) ≈ (1, 1.1504) — where line OP meets the line x = 1.

    FAQ

    What is tan 49°?

    tan 49° ≈ 1.1504

    Why does tan 49° 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°. 49° is not, so no such exact form exists; the value is used as a decimal: tan 49° ≈ 1.1504.

    Why does a calculator show −3.1729 for tan 49?

    The calculator is in radian mode (RAD): it takes tan 49 as the tangent of 49 radians, tan 49 rad ≈ −3.1729. Switch it to degrees (DEG): tan 49° ≈ 1.1504. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
