<p>Why don't they teach us this in AB? It seems so useful.</p>
<p>Because its probably seen as too rigorous for AB, when it isn’t.</p>
<p>I learned it in AB…</p>
<p>My AB book has it. We just won’t learn it in a while…</p>
<p>I just learned this like a week ago in AB. My teacher is incompetent though so basically taught myself the rule? :)</p>
<p>Last year, my Calc AB/AP teacher taught it. Its the best concept around when dealing with limits. Simple, yet easy.</p>
<p>I just learned it today.</p>
<p>Kind of.</p>
<p>Not really.</p>
<p>But kind of.</p>
<p>If this was taught in the Calc AB classes at my school, there would be catastrophe. The Calc teacher said that the AB students would just take the derivative randomly or use the quotient rule without knowing what they’re doing. I’m inclined to believe that this is true.</p>
<p>^That most likely wouldn’t happen. How hard would it be to take the derivative of the top and bottom of a fraction?</p>
<p>To be honest, I completely forgot L’Hopital’s rule. I haven’t used since BC two years ago.</p>
<p>we learned this in ab…</p>
<p>I think AB calculus should be very analytical. Although you personally may be strong in math, others who aren’t need the extra attention you give limits without L’Hopital’s rule to really understand what they’re doing. When you get to calc 2, or BC calc, you start to deal with a bunch of relative rates of growth, improper integrals, etc. and doing the limit the “long way” just gets tedious and inefficient.</p>
<p>I’m in BC and I think L’Hopital’s rule makes everything so much easier/simpler!!! But to each his own, I guess.</p>
<p>My online AB class didn’t include l’H</p>
<p>it is not that hard takes 1-2min to learn.</p>
