Solution inequality:
    Directly input the univariate inequality (that is, the inequality containing only one variable), set the angular unit (radian or angle) of the trigonometric function, and click the "Next" button to obtain the solution set of the inequality.
    It supports mathematical functions (including trigonometric functions).
