Give it a try:

```
(2^(1/2)+sin(p/2))/3
3^ 2 + 2 ^ 3
```

This page calculates the result of a constant expression. The expression is a string of characters, where the characters +, -, *, /, %, ^, represent addition, subtraction, multiplication, division, modulo, and power operations, combining some constants, the letters e and p represent The bottom e and the pi of the natural logarithm in mathematical operations can also be added with some functions. The parentheses can be used to change the priority of the calculation, thus acting as a calculator. For example, (2^(1/2)+sin(p/2))/3 means the square of the square of 2 plus the sine of the value of the dichotomy, and then divided by 3. Compared with the general calculator, this expression calculation has the advantage of facilitating the fractional operation. For example, one-third plus one-half is written as 1/3+1/2 and the result is also a score of 5/6. Therefore, it can be a good helper for mathematics students in large, medium and small schools, and a good computing tool for students. The table below lists the functions you can use. The list of supported functions is as follows (where x, a, b both represent any number or constant expression):

sin(x) | sine | cos(x) | cosine | asin(x) | Arcsine | acos(x) | Inverse cosine |

tan(x) | tangent | atan(x) | Arc tangent | exp(x) | exponential function | log(x) | Logarithm |

sqrt(x) | Square root | rand(x) | (0,1) random number | LE(a,b) | Less than or equal to, return 1 when a < = B, otherwise return0 | ||

LT(a,b) | Return 1 when a < b, otherwise return 0 | GE(a,b) | Return 1 if greater than or equal to, a > = B, otherwise return 0 | ||||

GT(a,b) | Greater than, a > b, return 1, otherwise return0 | abs(x) | absolute value | gam(x) | gamma function | ||

max(a,b) | Maximum value of a, B | min(a,b) | Minimum value of a, B | ||||

in(x,a,b) | x>Return 1 when a and a < = B, otherwise return 0 |
