WebExplanation: For sin 65 degrees, the angle 65° lies between 0° and 90° (First Quadrant ). Since sine function is positive in the first quadrant, thus sin 65° value = 0.9063077. . . ⇒ sin 65° = sin 425° = sin 785°, and so on. Note: Since, sine is an odd function, the value of sin (-65°) = -sin (65°). WebOnline arcsin(x) calculator. Inverse sine calculator.
