Not sure how to apply the Squeeze Theorem when not given in trig functions. My question is. Lim (x^2+1)=1 x→0 not sure what values lets call them K. ie -K≤x^2+≤K. for instances when I have. Lim xsin(1/x)=0 x→0 i say. -1≤sin(1/x)≤1 then multiply the whole inequality by x. -x≤xsin(1/x)≤x therefore limit as x approaches 0 of sin(1/x)=0 how would I do it for for non trig functions?
