I tutor high school kids and I've been compiling a list of ways that math can be useful in everyday life. One of the items on my list is "You can use calculus to fight a speeding ticket in court." I've heard professors making this claim and it makes sense given that you can use integrals in rate of change problems to determine the speed of an ( Read more... )

I have no idea how to approach this problem!

If f(x)={ e^x, x

Thanks so much to the people who helped me on my last FRQ: The FRQs are the only thing keeping my grade above a D (I failed two quizes, because I wasn't prepared Dx) I have another one to do, so if you could please help me again, I'd really appreciate it. I figured out most of it, I just need to be sure that its correct.

Hi and I am new here and I'm in serious need of rescuing ( Read more... )

I need a second pair of eyes. I have done something for my Calculus 3 class that is either clever or utter crap, and I am unsure of which. I am on the chapter for line integrals and have the following problem: A 160 lb man carries a 25 lb can of paint up a helical staircase that encircles a silo with a radius of 20 ft. Over the course of his climb ( Read more... )

I'm having trouble with this AP Calculus AB FRQ. I don't think my answer is right; does anyone know how to solve this / did I get it right? Thanks so much!

So, I have a calculus question on hand about double integrals and volume.  It's a practice problem without any solution, so I was wondering if people could give input ( Read more... )

This may be an irrelevant question, because I think it deals more with physics, but I am trying to figure out a formula where it shows how much force/pounds of pressure a car going at 60km/hr can produce ( Read more... )

So, I am in Calculus 3 right now and we are covering vector calculus. This week we are covering arc lengths ( Read more... )

I've got another question; I'm just starting vector cal, but I left my multivariable notes at home, so until I return to get them I'm struggling to remember how to do easy things like gradients ( Read more... )
