Your videos are far and away the best resource I've ever found online for these subjects. You've consistently helped me achieve excellent grades and I'm sure I'll be referring myself and others to your videos for many years to come. You're the best.

I realize I forgot to say thank you! I passed my entry exam to the university (maths, physics, chemistry) with really good marks thanks to your great videos. My course in Electrotechnical Engineering started one week ago and now I am back to refresh some concepts for calculus. I will probably return many, many times when my lectures get too confusing. Thank you so much for making my Engineering studies possible. As a working student, I need to find quick and efficient answers when I fail to understand something, and your videos are simply the best in this regard.

Take sqrt(-1) * sqrt(-1)
would that be equal to sqrt[(-1) * (-1)] = +1 or
would that be equal to i * i = -1 ?

Hi for the last problem why was the y (numerator ) on top and the x ( denominator ) on bottom? Can the answer still be X^2/Y^2?

[thomaspaul]

Where do you get the denominator of 2 from for the first problem?

[auctorutilis]

First of all, thank you.

But I stuck at question number 3.
