I don't understand why I'm not able to manipulate this quite basic function into another form
the function is:
But then this function is exactly the same:
Am I misunderstanding something basic here?
the actual question was to solve using Newtons method with the first approximation , if you cube both sides and do Newtons method:
but if you continue with the original equation without cubing both sides
Why are the solutions similar but not exactly the same?
