Solve for x and get points:

do your own homework! :P

Solve for x and get points:

 

D²x + x = 0

 

D²x = -x

 

D² = -x/x

 

D² = -1

 

D=i

 

-1(x) + x = 0

 

There's no way to solve for X, since that equation works for all numbers (-X +X will always equal zero for any value of X)

Actually, D and X are having a torrid affair, so D squared times X + X is really like a scandalous night with D reflected in a full length mirror while he tangles with X and her twin sister, X.

Hint: Simple harmonic oscillator

Alternate notation so as to clear up confusion:

 

x''(t) + x(t) = 0

Alternate notation so as to clear up confusion:

 

x''(t) + x(t) = 0

 

Oh. In that case, x=7

I didn't understand any of that and it gave me a headache even reading it. I can safely say I'm not a nerd. (I'm a dork)

I may be part geek... but nerdism evades me....

I left calc behind and vowed never to touch it again

I never had to take Calc

 

Best thing evar!

I hate you all.

Yeah, I took Pre-Calc last semester. I promptly started failing the course, and wound up failing the semester, even after being transfered to a lower math. Whoops. I traded my math class in for a Sign Language class this semester, though, which is good because I have no brain for the maths, yes.

This has gone way too far down the rabbit hole for my liking.

That's what she said

Nice one.
