    Angle (°)

    What is cos 341°?

    Answer

    cos 341° ≈
    0.9455

    Angle in radians: 341° = 341π/180. The point of the angle is in quadrant IV, where cosine is positive.

    ≈ — rounded to 4 decimal places. cos 341° can't be written with square roots: 341° is not a multiple of 3°.

    cos 341° = cos(360° − 19°) = cos 19° ≈ 0.9455

    P(cos 341°, sin 341°) ≈ (0.9455, −0.3256)

    FAQ

    What is cos 341°?

    cos 341° ≈ 0.9455

    Why does cos 341° 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°. 341° is not, so no such exact form exists; the value is used as a decimal: cos 341° ≈ 0.9455.

    Why does a calculator show −0.1368 for cos 341?

    The calculator is in radian mode (RAD): it takes cos 341 as the cosine of 341 radians, cos 341 rad ≈ −0.1368. Switch it to degrees (DEG): cos 341° ≈ 0.9455. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
