Hey /sci/ I need help integrating this and solving for y as

>>8542699
just punch it into wolfram

>>8542705
I did but for some reason the answer that I get won't allow me to plug in values and obtain a real output. I think wolfram assumes that all the variables can be complex and I don't know how to tell it to calm down.

>here it is

I'll post more about the actual problem. Making some figures now.

OP here,

Ok, here's the explanation of what I'm trying to do (will take a few posts).

I am using 3D seismic data (which are like echos underground) and trying to figure out how deep certain reflectors are.

To do this, I need to know the velocities of all the rocks above the reflector I'm interested in.

u sub with u = (c-a)e^(by)

>>8542793
Solved, this gives
[math]
x = \frac{1}{cb} ln((c-a)e^{by}) - \frac{1}{cb}ln(c-(c-a)e^{by})
[/math]

>>8542803
Ultimately solving for y gives
[math]
\frac{c-a}{cb} ln(e^{-cbx}+1) = y
[/math]

That hurt my feelings.

>y still on the right
You get what you paid for

>>8542835
astounding. Good eye.

>velocities of all the rocks
rocks don't move so these are zero you're welcome
