Best ResponseYou've already chosen the best response.0If l'Hopital doesn't work the first time but gives you the condition for it again, you can repeat it. You might have better luck the second time around.

Best ResponseYou've already chosen the best response.0One way is to use l'Hopital, but a faster way is to use the linear approximations for sine and tangent. The answer is 1/2.

Best ResponseYou've already chosen the best response.0THE DIFFERENTIAL IS SEC^2(X)/3+COS(x).numerator is 1 and denominator is 4 answer is 1/4 how did you get 1/2??????

Best ResponseYou've already chosen the best response.0pasta! skywalker94 is right! Using l'Hopital, we'll get 1/2. \[\lim_{x \rightarrow 0}(\tan2x/(3x+sinx))=\lim_{x \rightarrow 0}[2(1+\tan^{2}2x)/(3+cosx)]=1/2\]

Best ResponseYou've already chosen the best response.0use expansion method it is the fastest.... tanx = x + x^3/3............sinx = x  x^3/3!
