Roots
(Built-in Mathematica Symbol) Roots[lhs == rhs, var] yields a disjunction of equations which represent the roots of a polynomial equation.
lhs := rhs assigns rhs to be the delayed value of lhs. rhs is maintained in an unevaluated form. When lhs appears, it is replaced by rhs, evaluated afresh each time.
Slider
(Built-in Mathematica Symbol) Slider[x] represents a slider with setting x in the range 0 to 1. Slider[Dynamic[x]] takes the setting to be the dynamically updated current value of x, with the value of x ...
TransformationFunction[data] represents a transformation function that applies geometric and other transformations.
