No, that's the normal calculus for all the other majors. I have to debate whether or not I want to take the time to take the scientific calculus since that sets me back one quarter (my other classes, like chemistry and physics, have calculus pre-requisites/co-requisites), e.g. I cannot enroll in...

I'm not sure if your precalculus class differed from my own, but I found that I very rarely ever used anything covered in it in my calculus classes, except for knowing the natural logarithm/base e exists and a few trig functions/unit circle. I feel it can help with trigonometry, but not much...

Hm, I'll ask my friends if I can take a look at their textbook and notes and see the differences for myself, if that's okay. Yeah, that's been the pattern so far, but there are so many risks that I have to calculate between switching between maths. Yeah, my first physics class didn't use any...

Thank you for sharing this with me. I actually felt really alone because everyone around me in university did not really struggle with their math classes like I did, both in HS and university. Hearing somebody else do the self-teaching and succeed means a lot to me! I actually use that site...

I actually have pretty good memory so I can memorize formulas or write them on the allowed cheat sheets--it's just that I have no idea how to apply them. I can do pretty standard differentiation just fine, but deviate from that a little or force me to manipulate an equation, and I'll have no...

I'll go get that book then; thanks! Human Biology is just heavy biology/chemistry. I only take physics and calculus for one year each and then the rest of it is chemistry and biology. I'm pretty sure I'll need calculus for future physics classes and maybe some of population biology and...

Hey, thanks for replying! Writing the derivations step-by-step is a really good idea; do you happen to have any resources, though? Like an online book or tutorial? My math textbook is really terrible with this. I use Calculus, fifth edition, by Deborah Hughes-Hallett, et. al.; published by...

Hi, I think this belongs in this thread? I have a very weak math foundation stemming from high school. My Algebra II teacher was pretty bad, but it was my fault that I did not put the effort into learn and teach myself Algebra II. Then my geometry teacher was an easy A because she was new to...

Now that I think about it, it looks like I'm supposed to use dy/dx = ky instead of what I did in my attempt?

Oh, man. D: Thanks for pointing that out!

Homework Statement dL/dp = L/2, L(0) = 100. Find the solution to the differential equation, subject to the given initial condition. My textbook says the answer is L = 100ep/2, but I don't know how to get that answer (or e for that matter). Homework Equations ? The Attempt at a...

Thanks for replying! Yes, it's completely safe to assume that. :) I will try that, but I'm kind of confused as to why I'm computing kinetic energy? I thought that total mechanical energy would have to equal zero if it wasn't conserved, theoretically speaking.

Homework Statement Using the equation for the final velocity of an inelastic collision, show that mechanical energy is not conserved in the collision. (Do this only with variables.)Homework Equations Vf = (m1v1i + m2v2i)/(m1 + m2) KE = (1/2)mv2 TME = KE + PEThe Attempt at a Solution I honestly...

Thanks! I thought g was significant because you had the two sensors at an angle, basically one hanging off the other. But now I thought about it and this isn't the same as some other tension problems I've seen where one object is suspended in the air by a string. I'm assuming this censor is...

Homework Statement PROBLEM: Choose a pair of measurements of the forces from parts A5, A6, or A7, where the forces on the sensors were quite different. Imagine there was an angle between one cart and the string. Assuming that the larger force was the true tension in the string, what is the...
