I'm sorry, I wasn't exactly sure where to put this question but this section is probably my best bet. I'm basically trying to understand potential functions of more than 1 parameter... which is basically, most potential functions out there for molecular dynamics, what I just started working...
Actually I did something worse i think, but I didn't know it was not correct? I started with
2x - x3 ≥ 0
but then I did this: 2x ≥ x3 and then canceled the Xs...
so then I was left with
2 ≥ x2 ... leading to my original answer of sqrt(2) ≥ x
Why is this approach wrong...
What is the domain of sqrt(2x-x^3)
I thought this would be pretty straight forward but I am completely stumped. So obviously square root is not defined for (-inf, 0), therefore I said:
2x-x^3 >= 0
Working this out you get x <= sqrt(2) as the domain.
That is partially correct but I can't for...
