Formulas

A simple calculator and function graph.

Supported operations: +, -, *, /, ^
Predefined variables: pi, e, i
Predefined functions:

• ln(x)
• sin(x)
• cos(x)
• tan(x)
• asin(x)
• acos(x)
• atan(x)
• atan(y,x)
• sinh(x)
• cosh(x)
• tanh(x)
• arsinh(x)
• arcosh(x)
• artanh(x)
• fac(x)
• min(x1,x2,x3,...)
• max(x1,x2,x3,...)
• abs(x)

Functions for complex numbers:

• phi(c)
• x(c)
• y(c)

Lets you define variables:
a=30
b=40
c=(a^2+b^2)^0.5

and functions:
pyth(a,b)=(a^2+b^2)^0.5
pyth(30,40)

You may use hexadecimal, octal or binary numbers:
# hexadecimal
hex1=0x10
hex2=0h20

# binary
bin=0b1010

# octal
oct=0o3

Draw function graph with:
f(x)=3*sin(x)+x/5
:graph(f())

Draw polar function graph with:
flower(x)=5+cos(x*8)
:polar(flower())

Or specify the interval:
spiral(x)=x
:polar(spiral(),0,4pi,0.1)

Draw parameter graph with:
f(p)=5*sin(p)
g(p)=5*sin(p*10)
:param(f(),g(),-pi,pi,0.001)

All graphs have an additional parameter for the color in RGB:
:graph(sin(),0xff0000)

p(x)=3
:polar(p(),0x00ff00)

px(p)=sin(p)
py(p)=p
:param(px(),py(),-20,20,0.1,0x0000ff)
