When you enter a value in a matrix, you can use the following
Operations: * / - + ^
Functions:
sqrt(x) Calculates the square root of x
exp(x) Calculates e^x (e = Euler’s number)
ln(x) Calculates the natural logarithm (base e) of x
log(x) Calculates the logarithm (base 10) of x
sin(x) Calculates the sine of x
cos(x) Calculates the cosine of x
tan(x) Calculates the tangent of x
asin(x) Calculates the arcsine of x
acos(x) Calculates the arccosine of x
atan(x) Calculates the arctangent of x
The argument x can be a function. Example: log(sin(pi))
The argument x of the trigonometric functions is in radians
Costants:
pi 3.14159… Example: sin(2*pi)
e Euler number 2.71828… Example: 6e-5
On output, the values with point will be displayed with a fraction.
Graphing Calculator:
Sample expressions
simple expression: 1+2
variable evaluation: pi
function evaluation: sin(0)
variable definition: a=3.5
function definition: f(x)=x^2-1
parentheses: (1-x)^2
To enter an expression cointaining letters, such as sin(x), use the ⇳ key on the basic keypad. It toggles opened/closed the letter keypad.

perm(n,k): permutations
min(x,y), max(x,y)
floor(x), ceil(x)
abs(x): absolute value
sign(x): signum
rnd(): random value from [0,1). rnd(max): random value from [0, max).
gamma(x): (x-1)!
mod(x,y): modulo
Complex numbers
i or j is the complex base.
Example:

Operators
+ - × ÷ basic arithmetic
^ power
% percent
! factorial
# modulo
√ square root
' first derivative
Binary, octal, hexadecimal
Value converter in binary, octal or hexadecimal input prefixing respectively 0b, 0o, 0x, in decimal.
binary: 0b1010
octal: 0o17
hexa: 0x100
Derivative
It is possible to compute the first derivative of a function with one argument using the prime notation: log'(5).
The prime mark (quote) must appear immediately after the name of the function, and must be followed by open-parentheses.
The derivative may be plotted e.g. sqrt'(x).
To compute the derivative of an expression you must define the expression as a named function.
Eg f (x) = x ^ 2 + x, after insertion, type f '(x) to display the graph of the derivative.
