First off, thank you, this helps in my E&M class, second, I am going to school to teach physics, how on Earth do you produce a video like this? what software do you use and how did you get the board to do that???

Is this not the Newton-Raphson method? Raphson worked on the method before Newton.

10:50 Why does the spacing increases by a factor of two every time our number moves up by a factor of two pls ? How is it related to the exponent ?

If i had this same triangular wave but instead of being 1 at 0 it was 0 at 0 (so it would be a sine equivalent rather than a cos equivalent wave), is there an easy way to convert this?

Thank you for the great video! Is it possible for all the polynomials to be the same even when there are lots of dots to connect and one condition for all of them (say yi=xi^2)? Thanks!

Does this also mean LeftNull(A) & Col(A) are also orthogonal complements? Do they span all mx1 matrices?

@ProfJeffreyChasnov 24 дня назад
You can have access to MATLAB online if you join my Coursera course. You can audit for free, or pay to obtain a certificate of completion when you finish.

The only thing that I could not understand in the lecture is how PA=(PI)A makes things simple?
@ProfJeffreyChasnov
@ProfJeffreyChasnov Месяц назад
PI is the permutation of the rows of the identity matrix. It tells you what P is.

This video? I still didn't understand... It is only clear that red is real and blue is the imaginary part of the solution. Black is the absolute part. But the solution should be a hermite function for a certain value of energy, which is clearly not the case. Why the width of the black curve is like this is unclear... At least initial conditions are unclear...
@ProfJeffreyChasnov
@ProfJeffreyChasnov Месяц назад
Initial condition is a wavepacket. It is a linear superposition of many energy eigenfunctions.
@xelth
@xelth Месяц назад
@@ProfJeffreyChasnov Thank you. n1 ~ 50, n2 ~ 10? Are all lower levels occupied until the upper or states are also Gaussian excited? What do you think, hermite functions go into Fourier at n -> infinity?

I have computerised this a number of times, and arranged for all the pivots to be 1, to facilitate back substitution.
