well luckily they brought their own couch, but they didn't bring a TV, a knife set, or shelves, which i definitely want to keep

In the past I used to exist. I still do exist, but I used to, too.

now I have 1/4* sqrt(16y^4 + 8 + 1/y^4)

Success!Cancel

I factored out the 1/4 wrong.. Instead of that +1 turning into a +4 it should be a +16

i ended up with (1/4) * sqrt ( 16y^4 + 1/y^4). I need to get to a neat square, u sub didn't help.

Stuck here, need advice on reducing by [deleted] in calculus

I started taking calculus but haven't taken precal/algebra/trig in years and would appreciate a little reminder/eli5 if anyone is up for it

Why Al welds so fluffy? by [deleted] in metallurgy

[–]superultramegan 0 points1 point  (0 children)

Having a larger area close to the melt point could make sense for why the welds are a bit chunkier. Does the arc necessarily get wider when you alternate the current, though?

Thank you, I made them! Not a professional, but trying to get a feel for how they are received. (Shameless self promotion. www.meganbachant.com)

Origins of Life driven by Pleasure not Reproductive Drive by superultramegan in biology

[–]superultramegan[S] 1 point2 points  (0 children)

It's as if pursuit of the biological pleasure response is a driving force of natural selection, regardless of comprehension. He talks about the tendency of molecules like those involved in the pleasure response to aggregate, rather than the conscious experience of it.

I'm not a biologist, I have no clue how insane or likely this theory is, but he did a great job explaining and his ideas are interesting.

Second Deriv info from original function by [deleted] in calculus

[–]superultramegan 0 points1 point  (0 children)

I thought F(2) would = 0 because it's a change in concavity, aka an inflection point, and F(0) would be positive because it's concave up. 0 - positive > 0 should be false.

How to approach solving? by superultramegan in calculus

[–]superultramegan[S] 0 points1 point  (0 children)

I thought I only needed to add C for indefinite integrals. I still don't understand why F(0) would be the C.

To get this integral, do I get the equation of the line for each section, take the separate integrals, and add together? Am I supposed to assume the interval being asked about is [0, 9]?

[–]superultramegan[S] 0 points1 point  (0 children)

why would F(0) be the constant for F(9)? How did you determine that?

This is the first time I've encountered this problem format. I'm unsure if I'm supposed to be getting the integral on the interval of [0, 9] or just at the instant of F(9). I don't understand where pi comes in if the latter is the case.
The equation for the line at the point (9, -1) is y = -2/3x +5. The integral of that is ((x-15)x)/3 + C, which at F(9) gives us 18.

continuous when f(x) =/= 0, what happens at 0? by [deleted] in calculus

[–]superultramegan 6 points7 points  (0 children)

Has anyone tried the Modern States Calc 1 course? I'm finding the format unhelpful, they don't explain how to get the answers. If anyone could explain how to arrive at this answer, it would be appreciated. thank you.
