  • @Dtjuh91 I believe it is generally the same everywhere, I'm from Asia and I find these vids really useful

  • I was ready to hit my head against a wall when I couldn't get what my professor was talking about. Your videos have literally saved my life! Thank you soo much! :]

  • What would you do if you've got the component of axb (x is times, not the letter in this case), and the dot product of a and b, and you need to get the angle? I've asked around my campus, but no one seems to be able to explain it properly or in a way that I can understand.
