# How it work.

This widget allow to draw mathematical function. Enter function in the field in the top part of widget and press "Show".

You can enter following mathematical function:

## Basic operations

- Plus -> +
- Minus -> -
- Multiplication -> *
- Division -> /
- Mod -> %

## Trigonometric functions

- Sine -> sin(x)
- Cosine -> cos(x)
- Tangent -> tan(x)
- Cotangent -> cot(x)
- Secant -> sec(x)
- Cosecant -> csc(x)

- Arc sine -> arcsin(x) or asin(x)
- Arc cosine -> arccos(x) or acos(x)
- Arc tangent -> arctan(x) or atan(x)
- Arc cotangent -> arccot(x) or acot(x)

## Hyperbolic functions

- Hyperbolic sine -> sinh(x)
- Hyperbolic cosine -> cosh(x)
- Hyperbolic tangent -> tanh(x)
- Hyperbolic cotangent -> coth(x)
- Hyperbolic secant -> sech(x)
- Hyperbolic cosecant -> csch(x)

- Hyperbolic arc sine -> arcsinh(x) or asinh(x)
- Hyperbolic arc cosine -> arccosh(x) or acosh(x)
- Hyperbolic arc tangent -> arctanh(x) or atanh(x)
- Hyperbolic arc cotangent -> arccoth(x) or acoth(x)

## Square roots and degrees

- Square root -> sqrt(x)
- Degree -> pow(x, y) Variable x to the power y
- Root -> root(x, y) Root y of x

## Exponential and logarithm

- ex -> exp(x)
- Natural logarithm -> ln(x)
- Decimal logarithm -> log(x)

## Absolute number value

- |x| -> abs(x)

## Rounding

- round(x) -> rounding to the nearest whole number
- ceil(x) -> rounding to the nearest whole number in a big way
- floor(x) -> rounding to the nearest whole number the smaller side

# Constants

Also are available some constants:

- pi = 4 * atan(1) ≈ 3,141592653589793
- e = exp(1) ≈ 2.718281828459045

# Keyboard keys

esc -> reset widget
ctrl + left arrow -> graph will be moved left
ctrl + top arrow -> graph will be moved top
ctrl + right arrow -> graph will be moved right
ctrl + bottom arrow -> graph will be moved bottom

(You can view example. Do not forget to set accuracy in options if necessary.)

# Functions 2D

0.5*x+1
pow(x,2)-3
1/x
atan(x)
(x+1/x)/1.2
sin(10*x*x)*0.5
log(pow(x-2,2))
(x*x-5*x+5)*exp(x)/5
random()

# Functions 3D

sin(x)+cos(y)
sqrt(10-x*x)
atan(x)+atan(y)

#### Save graph

In some browsers when used display method "Canvas" you can save graph by clicking it with right mouse button and selecting "Save image". Also you can save 3D-graphs.

#### Offset

If graph isn't in the right place (larger than canvas) then can you set necessary parameters graph displaying in settings menu.
