Alright I need some Physics/Math Help

[James3shin]

This problem isn't exactly the Schrodinger, rather just the Classical Wave equation.

(d^2X/dx^2)=K*X(x) where K = Positive number

X(x) = C* e^((K^.5)*x)

(d^2X/dx^2)= C* e^((K^.5)*x) <--------WHAT HAPPENED TO K!?!?!?!

That's my question. I'm going over my notes and can't figure out what happened. Did I just not copy the professor properly?

 

[TheoPetro]

wouldnt (d^2X/dx^2)= K*C* e^((K^.5)*x)

YEAH! That's what it should read!!! But I swear I copied the professor, variable for variable and constant for constant.

Even for a professor it is easy to leave out a term

 

[TheoPetro]

ya profs screw alot of stuff up on the board. Linear algebra and ODE were the worst for that. If you know what youre doing and fallowing along you should have no problem correcting your notes as you take them.

C is a constant, so it appears your professor had the C absorb the K.

Edit: In other words, a constant times a positive number is still a constant.

Thanks homies, peace and love. May you two be blessed with broad chested women that carry out your bidding.

May MSParish get some love from broad chested women as well.

that works too. I hated Using C and K in ODE. I didnt get why you cant always combine the constants but maybe thats why im not getting a math intensive job.

Yeah he probably just absorbed the constant. It's a pretty common math thing.
