funcRtoR2

Converts a "f(t), g(t)" string to a function acceptable for [ClassCurve Curve]. If you pass a string to [ClassCurve Curve], funcRtoR2 will be used to convert it to a function.

Arguments

• funcRtoR2(expr, var, globals, locals)*

	expr		_*required*_		string in the form "f(t), g(t)"
	var		_default_="t"		name of the independent variable
	globals		_default_=None		dict of global variables used in the expression; you may want to use Python's builtin `globals()`
	locals		_default_=None		dict of local variables

All symbols from Python's [http://docs.python.org/lib/module-math.html math library] are in scope, so you can say things like "cos(t), sin(t)".

Example use of globals.

>>> funcRtoR2("c*t, c*t**2", globals={"c": 12})

This does the same thing.

>>> c = 12
>>> funcRtoR2("c*t, c*t**2", globals=globals())
