Hello, my professor just replied regarding this question, I no longer need help. Thanks though!

URGENT: Differential Equation Homework Statement Use suitable substitutions to solve the following equation: y' + xy = y^3 Homework Equations dy/dx + P(x)y = Q(x) I(x) = e^(integral(P(x)dx) y = (Integral of(I(x)Q(x)))/I(x) The Attempt at a Solution dy/dx + xy = y^3...

Hello, I don't post here very often, but I browse the threads nearly ever day. I would like to pose a question to those Scientists and Engineers browsing this forum: How does your current life compare to how it was in high school? Feel free to compare and contrast positives and negatives...

I've dealt with orange juice concentrate before, but I'm looking for a definition that would put it into either a "gel" or "not gel" category.

Hello. I was interested to see what everyone thought on this subject: Is frozen orange juice concentrate (Old South etc) considered a "gel"? My chemistry teacher suggested this, and I'm interested to see what other people on physics forums thought. Thanks.

Thanks, that really helped! Sorry that I may have posted it in the wrong forum.

Just a quick question about the Ti-83+ calculator. After you have hit the equals button to provide the solution for an equation, how do you get back into the equation to make any changes? The error key is not what I'm looking for, is it possible to make any changes you want in the equation? I...

Hello, I think you've made one small error on this question, in your equations it appears that you're looking for 1 velocity, when you're really looking for two. Your equation should look like this: (0.4)(2.5) = (0.4)(0.25) + (0.4)V2prime You already know one velocity, and you're...
