how to separate variables d^2u/dx^2=d^2u/dt^2-cd^4u/(dx^2dy^2), c is a constant
Is this a general math question, or a question in regard to Wolfram technologies?
This is a general math problem. Sorry about this as I am fairly new to the forum. Am I supposed to ask only Wolfram related questions?
Thank you for the information and sorry again about this. I will ask it somewhere else. I am sure there is a way because this is a homework problem on a textbook.
