Hello, I have the following code:
def f(a,b,c,x): xtemp=a for i in range(b,x): xtemp=xtemp-xtemp*c return xtemp var('t') plot(f(10000000,1,0.01,t),3,20)
and got the error
TypeError: range() integer end argument expected, got sage.symbolic.expression.Expression.
I understand that range does nor support 'var' object, but how can I have a variable range in this kind of function?
