very nice. you should add that before trying to calculate the inverse of a matrix (or the matrix from the inverse matrix) you should first check if it is linearly independent. edit: just checked and the grade of B is 2. so actually you should consider a quadratic matrix with lower grade. for example a 2x2 matrix extracted from B.
Thanks for watching & glad to hear that 😇 I will talk in detail about the linearly independent in the future because this is a different method to find or check the inverse of a matrix. I have mentioned at the end of the video about the formula which has adjugate (or adjoint) of a matrix which can be determined if the matrix has an inverse or not (by checking with the determinant of the matrix), also, I will try to compare the two methods. For the 2x2 matrix, you can see the following video: ua-cam.com/video/dALC_mvbs7E/v-deo.html
I'm glad that I Found this video on Reddit, I was really struggling but this video clarified all my questions.
Glad it helped & Good luck 😇
