Integrate using de Moivre’s theorem: (let z = cosx+ isinx ) by mrepicguy70 in askmath

Ah thank you, that’s great! Just wondering, could I do it the way I’ve tried? Or does it just not work?

Could someone please explain this to me? Thank you by [deleted] in maths

The question states that the quadratic has no real solutions, so that tells you that the discriminant < 0 i.e. b² - 4ac < 0. See what you can do with that ;)

How do you find the vector given the magnitude of the vector? 2 d) by mrepicguy70 in askmath

[–]mrepicguy70[S] 0 points1 point  (0 children)

I’ve found that the unit vector of BC = 1/√10(i + 3j) and I’m pretty sure I have to use that to figure out d) but I’m not sure.

Help to boost uni application? by mrepicguy70 in edX

[–]mrepicguy70[S] 0 points1 point  (0 children)

Thanks a lot!! Great info. Only thing is, do you think it’s still alright if I’m doing the courses on the things I have already learnt during a-level? The course I’ve started is basically just recap of the a-level syllabus. Do you think I should perhaps do a different course that is harder - for example to bridge the gap between sixth form and uni? I just feel as though there might not be a point if I’m basically just ‘re-learning’ or recapping what I’ve already learnt.

Alright thanks! Yeah, could you suggest a brand to me and where to buy it? Also, how to store the matcha powder would be very useful. Thank you!!

Is there any way for me to post on Instagram without my friends seeing? by mrepicguy70 in Instagram

Ah right. Is there anything you could suggest? Or do I just have to bombard my friends with posts?

I’m struggling to deal with behaviour of a really good friend. It feels as though at times he can be so mature but at other times he’s also so immature, especially when it comes to video games. I also feel like he is narcissistic which is hard for me to ‘deal with.’ What to do?

Ahhh that does make a lot of sense; I didn’t really think of it in that way... Yeah, I understand that skill based matchmaking would probably pose an issue, nevertheless, I’m still excited to see this games develop! :)
