I had trouble with d( V(x)/dx) = dV I know how to take derivative of a function, but I am not sure how to handle just a differential d( ) Congratulations on very well-presented video.

This video is very informative, I have only a small nitpick in the code: using omega = 1 we divide by sin(omega * a) = sin(a) = sin(3pi) = 0! The matrix indeed shows huge values (not infinity because of floating point rounding errors)

@@abolfazlmahmoodpoor_ will it be possible to get the pdf of the lecture. Also rather than matrix method will it be possible to solve simply by discretizing the second order differential equation. While doing the analytical solution, on the right hand side you assume the function to be independent of x but I think the function is dependent of x, in that case how to get the analytical solution. Please explain. Thank you.

@@sachinrajpandey5242In many cases the RHS is a function of coordinates and analytical solution does not exist. That is why we try to solve in numerically. I considered a constant RHS to have a analytical solution and compare it with the numerical one. What we did here, was discretizing the second order differential equation and solved it in both iterative method and direct method. About the sharing the PDF file, I am thinking about putting it in my Telegram channel but I think view hours of my videos will drop, and may be doesn't. I am not sure yet.
