f(x)=x^4-6x^2+2 f'(x)=4x^3-12x f'(x)=0 : 4x^3-12x=0 --> x(4x^2-12)=0 . Solutions : x1=0, x2=√3, x3=-√3 . These are the critical points . f''(x)=12x^2-12 . f''(0)=-12 --> -12<0 then x1=0

2009-11-19 Calculus:

Is that supposed to be f(x) = 2x/(x²+1)? The derivative f'(x) = ((x²+1)2 - 2x*2x)/(x²+1)². That simplifies to f(x) = 2/(x²+1)². The denominator is always positive, so there is 0, so there is no maximum
