Make sure your calculator is in radians mode. I suspect it is in degrees mode.

Please replace my teacher, she goes on about how slow your videos are while rushing through and messing everything up.

This guy! I swear without him I may as well just forget maths and further for a-level. Keep doing what you're doing! ❤️💪

I have a question.

Let's say z=1+i

Argument of z would then be equals to 45 degrees. How about the argument of 2z?
Do you take 2 times 45 degrees? Or is the argument of 2z still equals to 45 degrees?

Considering this video is over 8 years old you probably won’t read this but Thankyou so so much you have an excellent teaching style

Wait so
| a + bi | doesn't mean it is the absolute value of (a+bi)? Is this an exception where " | | " doesnt stand for absolute value?

For the love of god, i stuck in a problems for 30mn because I thought it mean Absolute value

[ExamSolutions_Maths]

Yep, I rely on donations and advertising
