Variable in integration

[CamilleLaflamme]

Hi, 

I have a simple problem.

I want to put a variable that is not yet define in a small equation. Then, I want to integrate it. But I have a problem because it does not recognize my x variable. All the other variables ( By, wf2, Cy) are define and as a number. 

(See de last page of my file)

Thank you !!

Define Vxb1 as a function of x.

Vxb1(x):=By - wf2.x

Then make sure you write Vxb1(x) in the integral.
