Hello, Can anyone help me with solving below and how to get "y" is as following:
EI*(d^4v/dx^4) +P*z= 0
Author said that using Mathlab, following equation is obtained.
y= - Pz^5/120*EI+C1*z^3/6+C2*z2/2+C3+C4

If you have symbolic toolbox, then try this
syms v(z) P EI
eq = EI*diff(v,4) == -P*z
v = dsolve(eq)
Result from live editor
Note that, I assumed in your question, d^4v/dz^4
