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).

Mathematical function:
Basic mathematical operation symbols: plus sign "+", minus sign "-", multiplication sign "*" or“ × ", division"/"or" ÷ "or":“
The natural constant e: for example, the third power of e: e3
Power: a to the power of b: a ^ b, for example: 2 to the power of 3: 2 ^ 3
Power function: a to the power of b, for example: 2 to the power of 7: 2 ^ 7
Square root: for example, square root of 9: sqrt (9) or sqrt9 or √ 9
Calculate the absolute value: for example, the absolute value of - 3: abs - 3 or abs (- 3)
Common logarithm function: for example, common logarithm of 3: lg3
Natural logarithm function: for example, natural logarithm of 3: ln3
Logarithmic function: the logarithm with a as the base b, for example, to find the logarithm with 3 as the base 27, use the function log (3,27)
