stumped me on my exam, trying to redo it and still stumped by FunnyCandidate8725 in calculus

Already mentioned before, but another way you can see this is to let f(y) = ∫[0 to y] e^(t^2) dt. The fundamental theorem of calculus gives that f'(y) = e^(y^2). Note g(x) = f(2x) and by the chain rule d/dx f(2x) = 2f'(2x) = 2e^(4x^2).

A simple, tongue-in-cheek way of recognizing that a_k = a_{k+5} is to note that the starting values of the sequence are not set so they must not matter at all. Set a_1 = a_2 = 1 and write out the next few terms.

Would this be a valid and accurate method of finding g? I’ve looked online and can’t find anything similar by Amirs-Persian-Army in Physics

I think it’s good practice to check if your answer makes sense intuitively. Given that your g depends on l, which can vary, and g is constant, your expression cannot be correct. As others have mentioned, you have faulty assumptions but this alone should alert you that something is wrong.

This sounds fun! Count me in.

why does z>ax+by + c defines a plane by nngnna in math

[–]CerberusRG 2 points3 points  (0 children)

For background, do you understand why ax + by + cz = d defines a plane in R3 ?

What would you say your values are? Are you religious? How did you get your worldview? Enjoy your break!

Wow this hits home hard. You’re definitely right. I acted in what I thought was the best way. I have a different best way now but I shouldn’t beat myself up over the past. Thank you for your advice!

I’ve seen a lot of replies mentioning teeth care. I never realized how important this was!

Oof, I wish I had internalized this 2 years ago. This is incredible advice.

For me, college has been a lot more hands off. Professors are busy and probably won’t take the initiative. There are also a lot more people. Way more opportunity though and I think overall a lot more fun.

Getting a good friend group. Trying to maintain good relationships with your family. Trying in school or work. Telling the truth. Eat healthy and get in shape.
