AP Calculus AB: Exam Prep Differential Equations FRQs

[@Coolgiy67]

This is it guys. Our whole year led up to a 2 question 45 min test 😭😭

[@jessicabecker3176]

im so scared

[@divinaa7276]

I am so nervous and stressed 😭😭

[@jsandov6]

You guys can do it! Recognize the FRQ and focus on what’s being asked....it’s pretty straight forward.

[@jsandov6]

Eshna Das, it’s ok to be nervous. Study smart. Focus on those FRQs we’ve done: Rate Accumulation, Graph Analysis, Differential Equations and Particle Motion...in that order of importance. Let’s hope and pray you get a Rate Accumulation and a Graph Analysis question but others think it might be a Differential Equations. You can do this, stay focused...remember you can use tour notes this year.

[@ShushSheldon]

Listen guys. It's gonna be alright. No matter what happens, just do your best, that's all that matters. Because, at the end of the day, the grade you get on this AP calc test will not have a major effect on your life in the grand scheme of things. What matters is that you're happy and healthy and your family is healthy. Be thankful and realize that many colleges understand that the AP tests taken this year will not completely demonstrate your abilities due to the circumstances we are in :).

what rule did you use to find the 2nd derivative of DH/dt how did you know to multiply -1/4 by itself

For part b. Why is it not just dh/dt... why is the -1/4 being multiplied if when you take a derivative the constant of a variable disappears??

[@ElEsMiguel]

8:02 Shouldn't it be negative at t=3? d^2h/dx^2 @ t=3 = 1/16 (3-27) = -24/16. This is a negative value and therefore is concave down. The line 1/16 (x-27) has its intercept at t=27, so everything below 27 is negative. Is this correct?

[@connork319]

No, you plug in H which is always 27> u don't plug in t

[@andrewphung3396]

When applying FTC given an initial point and a graph of a derivative, does the given point have to be on the bottom?

[@jsandov6]

Yes, the initial condition is your start.

[@andrewphung3396]

@@jsandov6 For example, in the Graph Analysis FRQs, I know F(8) is given but for me, I start with 0 as my lower limit and 8 as my upper limit. I still get the same answer. Because instead of yours where your work shows f(0)- f(8) from the integral of f'(x) on 8 to 0, I make mine the integral of 0 to 8 = f(8) - f(0). I get the same answer but I am not sure if the scoring will be different because of this.
