This is so much better than Khan Academy. Khan Academy makes it so stupidly confusing, drawing lines everywhere etc. This is nice, and simple. Thank you

[@MaxUP2]

So true. He goes on for 20 mins with no examples.

[@shiah4901]

so true lol, khan academy was literally a waste of my time for this chapter

I think if you multiply the matrix for 45 degrees by square root 2 rather than reciprocal ? Also this was the best explanation for rotation transformations I've seen so far.

What about in R3 about the x axis and the z axis.

[@jousif650]

You are incredible good. Thanks a lot

Thanks !

Sin45 or cos45 doesn't equal that you write its equal to under root 1/2

[@davidalvarado8404]

wrong

[@kubawharton]

What is wrong? I think this is better than lots of repeting theory, because this is illustrating. Exampels are always needed.

Thanks!
