The beautiful teacher, Wang Lili, paused for a moment and then began, "Um... Today, I'm going to teach you some knowledge about mathematical physics equations. Of course, it won't be the homogeneous equations you've learned in class but rather..."
"Today's key content: the Green Function method for the two-dimensional Laplace equation..."
As soon as these words were out, the class erupted in groans.
Ye Kaifu finally understood why the first three rows were empty.
This course must be a bomb!
The usual final questions in math exams, such as Fourier Transforms, orthogonal expansions, ordinary differential equations, and so on, had become routine tools here. Could it not be difficult?
Without saying much more, the teacher officially began the class.
"Dear students, I believe you've all learned homogeneous partial differential equations and non-homogeneous partial differential equations. Due to time constraints, we're not going to review them here..."
