Gosh. Are you guys using the quotient rule when you're doing your derivative of (x^3)/x?? Or are you just doing the derivative of x^2...
If you do the quotient rule it turns out to be 3x - x...Which is what Kalovale got by bringing the x up to -1 power and using product rule.
Dammit 21whatshisface is right. The minimum is close to 0 but not 0.
That's quite interesting cause i don't spot that using the quotient rule. Though it's technically right.
dy/dx = [x*(3x^2)- (x^3)*1] / x^2 = [3x^3 - x^3] / x^2 = 2 x^3/x^2 = 2x. Or you can keep it as the fraction... either way.
Edit: Oh wait i see it... why would you split up the fraction though? xd
