transgalactic Posted February 20, 2009 Posted February 20, 2009 f(x) and g(x) are differentiable on 0 f(0)=g(0)=0 calculate [math] \lim _{x->0}\frac{cosf(x)-cosg(x)}{x^2} [/math] ?? it looks like cauchys mean value theorem F(x)=cos(f(x)) G(x)=cos(g(x)) what to do next??
WhataBohr Posted April 17, 2009 Posted April 17, 2009 seems odd.. you might want to look at rolle theorem perhaps
