Yes the first one but I am not sure about the second
Yes sinx/x
The limit one approaches infinity =0
@harsh98 I believe the sin was one of the answers to a limit problem. I honestly believe I put that. But I have no clue if it is right. I think it asked if the limit approached 0 and I just guessed that one.
Honestly, what the heck would be the integral of arcsin?
It’s right. It’s only wrong if the limit was to 0, since by squeeze theorem, it would be 1.
For infinity, sin never becomes greater than x , so yes , 0.
I didn’t bother memorizing the arc-trig functions. Wasn’t worth keeping 6 formulas in my head for 1 or 2 questions. lol
For the last question on the frq, I said 1/2 f’(x) because the 2x was u and you had to put in in terms of u . du
non calculator was harder than calculator on multiple choice
@harsh98 That’s what I did as well. I got 7/2 as the answer.
Yes and there was a question that said something lim x —> infinity f(x)/ something idk and lim x—> infinity f(x)/ 3^x = 0. I put e^x for that
What did anyone get for C? I can’t remember what I ended up with. I remember the ln(x-1)+c=x something. But I can’t remember the initial condition and all
I put pi/72 for the arcsin question lol idk what I was doing. I found the non calculator MC pretty hard.
tanked the funnel question
@harsh98 that was a different question and it was pi^2/72.
Ya calculator section i finished with 20 minutes left of the multiple choice.
Yeah pi^2/72 was right for arcsin. I ended up putting it in my calculator to Ease my mind after the test haha
Yeah I thought the first 28 were the hardest of the exam. The non-calc FRQ’s were fairly easy except for the funnel one.
Was the answer function is both continuous and differentiable?
@harsh98 Yes, I got pi/72 for something too.
@Chrysanthemum14 Yes I’m pretty sure it is 7/2. Many people seem to be getting 7 but I think they forgot to complete the chain rule.
@YoohooAddict For approximation of 2.1 I think I got 3.6. I also got 7/2 instead of 7 because the u’ would be 2. I got everything else the same though.
What choice was that c? CAuse i guessed c
I am not sure but i just guessed both. It was definitely continuous
