How it works

This widget allow to draw mathematical function. Enter function in the field in the top part of widget and press "Show". Open the "Fonctions" menu to modify the current function or add a new function.

You can enter following mathematical functions :

Basic operations

• Plus -> +
• Minus -> -
• Multiplication -> *
• Division -> /
• Modulus -> %

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)

Power and root

• Square root -> sqrt(x)
• Power -> pow(x, y) Élève x à la puissance y
• Root -> root(x, y) Root y de x

Exponential and logarithm

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

Absolute value

• |x| -> abs(x)

Rounding

• round(x) -> round to the nearest integer
• ceil(x) -> round to the first integer bigger than x
• floor(x) -> round to the first integer lower than x

Constants

Some constants are also available :

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

2D Fonctions

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

3D Fonctions

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