#13 is different from the pdf file in the description. the one in the description is a composite function of f and g while yours is the product of them both. The answer for the one in the pdf would be c(2)
Mr., thank you for your amazing video! I have one quick question about the leading coefficient. 4:54 Does the rule only apply to lim x-> negative infinity? How about lim x-> infinity?
Thank you for your kind words! Yes, that rule applies for limits at plus or minus infinity. I hope your school year is going well. What topic(s) are most challenging so far?
@@vinteachesmath Thank you so much for your reply, professor! Hope you are doing well as well! Do you mean that lim x->plus infinity e^x also equals 0? Actually, I am not quite confident on every units because my teacher just skipped a few concepts on each unit and let us self study, but I will practice with your video later when I finish completing questions in this video.
@@ANMULIYA369 The limit as x approaches infinity of e^x diverges to infinity. The leading term trick just means that when you have multiple terms attached by addition and subtraction, you can take the limit as x approaches plus or minus infinity of just the leading terms on top and bottom. The limit as x approaches + or - infinity of exponential terms is a little bit of a thought experiment. With exp functions, on side of the graph approaches an asymptote, while the other side diverges.
Hello! This video was so good! Can you please confirm if this video (and any other ones of the same type) are around the same difficulty as Calc BC? thanks
I would say so; I designed these questions by looking at old exams and other college board sample items that were released to the public. I would also look for old FRQ's, try to go through the most challenging examples. Which topic(s) are you struggling with the most?
For the last question last part c, the limit function is 3 (x+2)/(x-3), substitute x by b, and equal it to 10, solve it and the b=36/7. Can we do that?
for the question in the calculator section, number one in c, can I say that f(1) has a point discontinuity and still get the question correct? ty for the videos.
I would say "f(x) has a point of discontinuity at x =1." f(1) is a point of discontinuity is misleading because f(1) is undefined and in other examples, f(1) could refer to the function value at a location other than the connected portion of the curve.
I'm happy to help! Hang in there. Calculus is one of those classes you have to grow into. I have practice tests for most of the units, and I am currently putting together a practice test for unit 4

Thanks for letting me know! I edited the pdf to match the video!
it was very helpful!! thank you
Glad it was helpful! I hope your AP test prep is going well! Thanks for supporting the channel.

thank you for this 😭 i was sure to fail if not of your video

will doing these problems be enough for ap calc bc? I'm in a rush since I don't have practice and my exam is tomr
At this point, I would look at full exams, covering all 10 units. Good luck tomorrow!
