First teacher who just doesn't start solving questions but helps understand the concept behind the mathematical topic...love it❤

Sir, just watched your lecture on sum of all the counting no. and I got surprised by the conclusion but it was the most passionate explaination i have ever watched. Love from INDIA

Mr.woo can you do a very difficult math equation that takes up two white boards

I find it cool that everyone is speaking about angles just in radiants (pi/4), not even once mentioning the 45°. Do you usually have angle measurement devices measured in parts of pi?

i thought the same. My head the whole time just said: 90 and 45 degrees. I felt so dumb for having thought in degrees not radians

It's worth actually trying to understand it. As long as you know what i means, and the definition of complex number, and then what the Complex plane / Gauss plane means. A complex number looks like this: a + bi, where a and b are real numbers, and i = sqrt(-1) as explained below. i is a short for writing the square root of -1. It seems counter intuitive and impossible, but once you multiply i 's together you get interesting results, such as: i ^ 2 = sqrt(-1)^2 = -1 i ^ 3 = i ^ 2 * i = -1 * i = -i i ^ 4 = i ^ 2 * i ^ 2 = (-1) * (-1) = 1 Put this in a complex plane, Where the "x" axis it the real number, and the "y" axis is the imaginary's coefficient. You can see that between i and i^2 there is 90 degrees, or pi/4, then between i^2 and i^3 the same, and between i^3 and i^4 the same. Complex numbers are a great way to rotate vectors in a rational manner, not in an angular manner. There are many advantages to using rational rotation over angle rotation in computer graphics and aerodynamics. Even if you won't use this, maybe someone will so... I'm gonna put this here.

most of the people claims that he is the best teacher in mathematics, I agree on it, but he is not only the best, you can find lots of teachers like him and even more better than him, in Nepal and India, 😊😊
