Chapter 1 / Ch.1.1 - 8
« Last post by Emman Subhani on January 22, 2023, 07:14:01 PM »Ch.1.1- 8 :xux +yuy + zuz =0
For this question, I see that xux + yuy is Linear Homogenous. However, looking at zuz, I believe that the most precise answer for this question is Linear Homogenous as well right?

I understand that the first part of the equation ( $u_t +u_{xxxx}$) is definitely Linear Homogenous. However, the $u$ in the last part is confusing me and I am stuck between two answers - linear homogenous or semi linear?
