    Angle (°)

    What is sin 26°?

    Answer

    sin 26° ≈
    0.4384

    Angle in radians: 26° = 13π/90. The point of the angle is in quadrant I, where sine is positive.

    ≈ — rounded to 4 decimal places. sin 26° can't be written with square roots: 26° is not a multiple of 3°.

    P(cos 26°, sin 26°) ≈ (0.8988, 0.4384)

    FAQ

    What is sin 26°?

    sin 26° ≈ 0.4384

    Why does sin 26° 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°. 26° is not, so no such exact form exists; the value is used as a decimal: sin 26° ≈ 0.4384.

    Why does a calculator show 0.7626 for sin 26?

    The calculator is in radian mode (RAD): it takes sin 26 as the sine of 26 radians, sin 26 rad ≈ 0.7626. Switch it to degrees (DEG): sin 26° ≈ 0.4384. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
