Here is a complete list of all functions you can use in Function Guessr.

Arithmetic

Function	Syntax	Description	Example
Addition	`a + b`	Adds two values.	`x + 1`
Subtraction	`a - b`	Subtracts the second value from the first.	`x - 2`
Multiplication	`a * b`	Multiplies two values.	`2 * x`
Division	`a / b`	Divides the first value by the second.	`x / 2`
Power	`a ^ b`	Raises `a` to the power of `b`.	`x ^ 2`
Square Root	`sqrt(x)`	Returns the square root of `x` ( $x \ge 0$ ).	`sqrt(x)`

Trigonometric

Function	Syntax	Description	Example
Sine	`sin(x)`	Sine of `x` (radians).	`sin(x)`
Cosine	`cos(x)`	Cosine of `x` (radians).	`cos(x)`
Tangent	`tan(x)`	Tangent of `x` (radians).	`tan(x)`

Inverse Trigonometric

Function	Syntax	Description	Example
Arcsin	`asin(x)`	Inverse sine. Result in $[-\pi/2, \pi/2]$ .	`asin(x)`
Arccos	`acos(x)`	Inverse cosine. Result in $[0, \pi]$ .	`acos(x)`

Function	Syntax	Description	Example
Exponential	`exp(x)`	$e^x$ (base $e \approx 2.718$ ).	`exp(x)`
Logarithm	`log(x)` or `ln(x)`	Natural logarithm (base $e$ ) of `x` ( $x > 0$ ).	`log(x)`

Utility & Step Functions

Function	Syntax	Description	Example
Absolute Value	`abs(x)`	Returns the magnitude of `x`.	`abs(x)`
Round	`round(x)`	Rounds to the nearest integer.	`round(x)`
Floor	`floor(x)`	Rounds down to the nearest integer.	`floor(x)`
Ceil	`ceil(x)`	Rounds up to the nearest integer.	`ceil(x)`
Sign	`sign(x)`	Returns -1, 0, or 1 based on sign of `x`.	`sign(x)`
Maximum	`max(a, b)`	Returns the larger of `a` and `b`.	`max(x, 0)`
Minimum	`min(a, b)`	Returns the smaller of `a` and `b`.	`min(x, 1)`
