    Angle (°)

    What is sin 341°?

    Answer

    sin 341° ≈
    −0.3256

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

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

    sin 341° = sin(360° − 19°) = −sin 19° ≈ −0.3256

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

    FAQ

    What is sin 341°?

    sin 341° ≈ −0.3256

    Why does sin 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: sin 341° ≈ −0.3256.

    Why does a calculator show 0.9906 for sin 341?

    The calculator is in radian mode (RAD): it takes sin 341 as the sine of 341 radians, sin 341 rad ≈ 0.9906. Switch it to degrees (DEG): sin 341° ≈ −0.3256. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
