Sir, I got half of my answers wrong as I put in the "i" after the number. Instead of the mark I should have gotten it was extremely low even though I had put the correct answers in. I took a screen shot for proof to show you tomorrow. Thank you Sir.
I believe you.
Sorry sir but if you have a chance either tomorrow in class could you please explain question 20 on complex numbers http://www.mathsireland.com/LCHGeneralNotes/Complex_Numbers/2_9_DeMoivre_Find_Powers_Complex_Numbers/Q_2_9_DeMoivre_Find_Powers_Complex_Numbers.html
The pink background thing? I don't know where the root 2 or pie over 4 came from sorry I can't find the symbols on this
I have posted an explanation to this now - I hope its useful?
Sorry to be a plaque but I did terrible in that test thing and am wondering if I'm doing the questions wrong or if I'm not writing it correct but I didn't use i? The retest would be good now :L
Not to worry - we'll look at this tomorrow. Keep up the hard work.
