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:

To enter an expression cointaining letters, such as sin(x), use the ⇳ key on the basic keypad. It toggles opened/closed the letter keypad.

--Logarithms and power

sqrt(x): square root; x^0.5
cbrt(x): cube root; x^(1/3)
exp(x): exponential; e^x
log(x), ln(x): natural logarithm
log2(x), lb(x): binary logarithm
log10(x), lg(x): decimal logarithm
log(base,x): arbitrary base logarithm

--Trigonometric - radians

sin(x), cos(x), tan(x)
asin(x), acos(x), atan(x)

--Trigonometric - degrees

sind(x), cosd(x), tand(x)
asind(x), acosd(x), atand(x)

--Hyperbolic

sinh(x), cosh(x), tanh(x)
asinh(x), acosh(x), atanh(x)

--Other

gcd(x,y): greatest common divisor
comb(n,k): combinations
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:

i*i
(1+i)^2
e^(i*pi)

--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.

--Multi plot

To plot multiple functions on the same 2d graph, simply enter them on the same line separated by ";".

Once you have drawn the graph of a function, whether it is 2D or 3D, it will be possible to zoom, to turn, change the scale etc. Moreover by pressing the menu is possible to save a screenshot of the graph.
