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) ou asin(x)
• Arc cosine -> arccos(x) ou acos(x)
• Arc tangent -> arctan(x) ou atan(x)
• Arc cotangent -> arccot(x) ou 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.)

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.

Current
f(x) = x
