Hi, the centre (the X Axis) is where Y is equal to zero. The Y axis is where X is equal to zero. Thanks 😊

you forgot to mention about formula of phase to radian from sin 30 degree = n/6 which is coming from 2.phi divided by 360 degree = (2n/360 degree)

6:34 isn’t the frequency of the shown graph 1/(2pi). Because the graph shown has a period equal to 2pi.

Hi, at the time you mentioned, the circuit has done one cycle in 2pi radians. Remember, the x axis here is in radians, not seconds. A one Hz signal will always spin through 2pi radians or 360 degrees in one second. I hope this helps!

Hi Dillinger, it's great to hear comments like this. It took months to make and it's worth it when people take the time to comment, especially when it helps people understand. My teachers many years ago skipped so much, so it was a challenge to understand, back in the 1990s. Take care and feel free to share. See also Electronics4engineers channel. Thanks again, James.

Jay - A good question. The 3x3 video is going to be uploaded later today. The matrix must be square (3x3, 4x4, .. nxn). In order to find det(J) for matrix J, we need to take the first row of elements and multiply them by their respective minors (the mini 2x2 matrix determinant around them). See www.mathcentre.ac.uk/resources/uploaded/sigma-matrices9-2009-1.pdf Video to explain will be up soon :) All resources shared on our community. Good question, James.

How would this work if the matrix was say 3x3 or 3x4, does it only work with 2x2 matrices?
