Ooh, a mistake by Mr Woo here. You don't see many of those. He said "root 2 squared plus root 2 squared does indeed give me 4", except c squared is 16! Oops. It should be sqrt(8), or 2*sqrt(2)
The angle in question is a 45 degree angle with a radius of 4. Then each side is 2 x the square root fo 2. This is proven by a^2 +b^2. = 4^2 which is 16. But a =b so we can say that 2 x a^2 = 16 or a^2 = 8. Therefor a = 2 x the square root of 2. And so does b. I follow this example in Algebra 11 a Modern Course by Vanetta, Goodwin and Fawcet. So the complex form is 2xsquare root of 2 CIS 45 degrees. Not sure what I did wrong here.
you guys are lucky to have some teachers like this man
Shouldn't it be 2*sqrt(2) because the radius is 4 not 2?
That is what I kept getting: 4/sqrt(2) = 2*sqrt(2).
yeah sqrt(2)/2 times unit 4 equals 2*sqrt(2), the unit is not 2
Isn't the modulus defined as the Square Root of (a^2 + b^2) ? So why |z| = 4 and not 2 ?

The red whiteboard marker in the corner is feeling neglected.
it's used to write the super important points to watch out for..!
Bro the Arc Complex Master Level in doom eternal got buffed wtf they doin math now.
Good I love your teaching
Very helpful!

My guess is that Eddie trusted the student who answered without double checking.
Is this trig?
Our schools in India are happy to open schools for exams, not teaching.....
wow you rlly don't age
