Yes, I have studied calculus and differential equations, and solved many different types of problems, but I am unable to solve this specific problem. When I wrote "new" I meant that I had not studied differential equations for several years Thanks Ocifer, now I am one step further, will update...

I would like to derive the air resistance equation showed in the attached photo. A little while ago, I tried asking at a different forum, however, the users were very experienced and omitted several stages of the derivation, and thereby made the interpretation difficult as I am new to math, but...

Thank you very very much you have been a great help!

Yeah, I tried that but couldn't come up with your result. For your information, I use a N-spire calculator.

Thanks for your help. I have a few questions for your solution - 1) Why are the position of the constants changed inside the radical in (3) – I am thinking they should be the same. 2) When I try to isolate ”v” I end up with a fraction - how did you go from (3) to (4) I'm still new to all...

I have been unable to solve this problem featured in "Elementary Differential Equations" by Edwards and Penney. The problem is this: I do not know how to integrate the function, and get the desired result. I would very much appreciated any help and instructions on how to get the two air...
