First line of buttons are for algebra to return function, second line of button are for calculus to return function, third line of buttions are for discrete math with default index variable k to return value, forth line of buttions are for numeric compution to return number. 5th and 6th line of buttions are to plot2D graph. 7th and 8th lines of buttion are to plot3D graph.

The same color buttons are a pair of inverse operators, its result can be checked each other if it returns origial function or not.

Rules:

put function arguments in parentheses: sin(x) -- correct, sin x -- incorrect; do not omit multiplication: x*sin(x) -- correct, x sin(x) -- incorrect. x**y or pow(x,y) for power. Usual keywords are lowercase, which are different from uppercase, e.g. sin is different from Sin. Its default variable is small letter x, but its default index variable in discrete math is k.

Example:

Add new function f(x) = `x^2`; call f(2)
f(x) = x^2; f(2)

Add new rule of derivative `d/dx` f(x_) := sin(x)
d(f(x_), x_) := sin(x);

Add new rule of integral `int` f(x) dx := F(x)
integrate(f(x_), x_) := cos(x);
