    What is sin 134°?

    Answer

    sin 134° ≈
    0.7193

    Angle in radians: 134° = 67π/90. The point of the angle is in quadrant II, where sine is positive.

    ≈ — rounded to 4 decimal places. sin 134° can't be written with square roots: 134° is not a multiple of 3°.

    sin 134° = sin(180° − 46°) = sin 46° ≈ 0.7193

    P(cos 134°, sin 134°) ≈ (−0.6947, 0.7193)

    FAQ

    What is sin 134°?

    sin 134° ≈ 0.7193

    Why does sin 134° 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°. 134° is not, so no such exact form exists; the value is used as a decimal: sin 134° ≈ 0.7193.

    Why does a calculator show 0.8859 for sin 134?

    The calculator is in radian mode (RAD): it takes sin 134 as the sine of 134 radians, sin 134 rad ≈ 0.8859. Switch it to degrees (DEG): sin 134° ≈ 0.7193. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
