MR. Organic Chemistry Tutor, thank you for a basic introduction to Imaginary Numbers. Imaginary numbers exist everywhere in math, science and engineering.

Thanks sir, you just summarised my whole text book chapters on Complex numbers 💯

I have just encountered complex numbers for the first time while calculating the magnitude of frequency transfer in an RC filter in a college class. Had no idea what a complex number even is, but now I understand what is going on. Thanks a lot!

7:03 For the (4-3i)(4+3i) you can use the formula a^2-b^2 = (a + b)(a - b) so it would be 16-9i^2 just like your answer. This is just a faster way to do it. Hope this helps!

You're the goat, you're saving so much time by cutting the fluff I experience in class and teaching in a straight forward way. Now I'm skipping more class and just watching you to learn how to do my homework and for review for tests. Saving a lot of time and stress.
