Calc Final Exam Review 1

[cmilkau]

The temptation to just write "the limit doesn't exist" ...

[yorshvences]

The color coding is everything, you are definitely professional at this aspect of mathematics 🧐🤓🤜🤙

I already took Calc 3 and I don’t even remember any of this

[AVLife]

Wow thank you, you have a good way of explaining these which is both concise yet effective

this was our highschool exams lol. where's the epsilon-delta definiton of limits? had a quiz in calc 1 today (which i failed last year) had explaining why a limit f(x) was equal to some real number using epsilon-delta definiton, couldn't think of anything so i just wrote some random stuff lmao

in chile we study this topics at school lol

The solution for question e is:

lim
x->0 ( 2tan(2x)(-sin(x)/cos^3(x)) + 4sec^2(x)sec^2(x)) = 4

[wavingbuddy]

You didn't have time for e)? It takes like 1 minute? It's just the product rule on 4sec^2(2x)tan(2x) to get 16tan^2(2x)sec^2(2x) + 8sec^4(2x)

I was with you until you actually wrote the division symbol at 14:10. What? No one uses that past elementary school. Just move the 2x to the bottom.

*L'Hopital (not L'Hospital, ha)

Its very simple no way some students can get under 100%
