***AP Calculus AB 2015-2016 Thread***

I think I got 8060 for the Riemann

Man the velocity frq was super easy i think imma get 9 points

On the triangle graph FRQ what did you guys put for part b (whether g(x) had a poi at x=4 or not)?

I put yes because I did a whole g"(x) number line but when that part of the exam was over I started thinking about how g"(x) doesn’t even exist at x=4 so now I’m worried.

-2 abs min and 6 abs max right?

Forreal: 9/9 for sure

Yes, b/c sign changes and PoI can be DNE.

Any other questions yall remember lol

@Kelvas I think it was 109/6 because it was 50/3 + 3/2 and then I simplified. I don’t remember what question it was though lol.

But it’s a tenth of that value right. so 1/10 (109/6)= 109/60

I got 22pi for the concurrent circles questions. Anyone else?

yea

@Chrysanthemum14 for the poi it does exist because it doesn’t matter if it’s undefined or not for point of inflection, it changes signs

it exists

Lol ok so I think the hardest questions were solving the dq and that blasted funnel. I wanted to funnel it down my throat!

What about the inverse where they gave you f and like g(5)=0. How did you do that one.

And then I made a careless mistake on 1c and 1d probably but i think i got at least 7/9 on everything else…am I on track for a 5?

How did you do the min and max. Dont you just plug the endpoints first and then deal with critical numbers. I remember changing signs on the integral and stuff like negating stuff.

Speeding up or slowing down??

I just did the area under the curve from 2. But you could also use the derivative to find where it changed sign. @harsh98

If I got 7 in my last frq, will I get a partial credit?
