Differential equation

[profliz]

Hi guys!

Needa Ya help with Mathcad. I'm trying to solve differential equation and getting troubled with that. (See attachment:

at yellow highlited region).

Mathcad says that it has too few initial conditions, but when I use sign (') [Ctrl+F7] for derivative it returns an error like that: "This value must be a function but has the form:any1".

What seems to be a problem? Any suggestions? It's obvious that initial conditions are ok and are sufficient to solve this analytically.

Thanks in advance!

You say, it is all defined, but, just looking at it, I see no definitions for Iy, M01(x) or Mo2(x).

M01(x) and M02(x) are defined just above "Given".

Iy is a cross-section constant - moment of intertia, I just forgot to paste it into the uploaded file. If I define it, there is no change - Mathcad still doesn't calculate..

Any ideas?
