WebbOnline arcsin(x) calculator. Inverse sine calculator. Enter the sine value, select degrees (°) or radians (rad) and press the = button. WebbUsing arcsine to solve trigonometric equations Arcsine can also be used to solve trigonometric equations involving the sine function. Examples: Solve the following trigonometric equations for x where 0≤x<2π. 1. 2sin (x) = 2sin (x) = sin (x) = Sine is positive in two quadrants, quadrant I and quadrant II, so there are two solutions: x= and x=.
