def EulersMethod(self, numberOfSteps): # Repeate linear approximation
over an even range
e = 1 # e**0 = 1
for step in range(numberOfSteps):
e = self.linearApproximation(e,1.0/numberOfSteps,e) # if f(x)=
e**x, f'(x)=f(x)
return e
This is your code, right?
I'm not seeing anywhere in here that creates a list of numbers. It
does exactly what you're hoping for: it feeds the answer back to
itself for the next step.
