Renegade343 Posted August 26, 2014 Author Share Posted August 26, 2014 The amount of maths is surprising here, out of curiosity are you studying at uni or something? Maybe. Link to comment Share on other sites More sharing options...
Niryco Posted August 26, 2014 Share Posted August 26, 2014 (edited) No. I already know what limits are. What I mean is for that question you gave me, what are the limits? usually proving the limits are to n or infinity if i remembered correctly. Maybe. Teach me senpai!

Renegade343 Posted August 26, 2014 Author Share Posted August 26, 2014 (edited) usually proving the limits are to n or infinity if i remembered correctly. Alright then, since I was wondering if that particular question would have x having a limit between -2π to 2π or something of the sort (i.e.: Not infinity). EDIT: Re-read the question, and I already solved it in my mind. And I think it should be sin(x)' = cos(x), not sin(x)' = -cos(x), if we use limits.

Prany Posted August 26, 2014 Share Posted August 26, 2014 Oh, look, thread about math. And I'm reading it. This is the moment when I take a break from forums and Warframe in general. :P Link to comment Share on other sites More sharing options...
Niryco Posted August 26, 2014 Share Posted August 26, 2014 Yes. Oh so you are a survivor! I need a ride quick, my boats sinking from all the thinking. Right now the worse thing that i fear is PGF euler's distribution.... if i even got that right. What option topic did you take for math hl?

Further Statistics and Probability (although I tend to forget the things within that particular option, for some reason. I fare better when I self-studied set theory options).

I fare better when I self-studied set theory options). HAHHAHAH we are on the same options too! I read up abit on set theory but couldn't find the actual book to self study. Also since the math HL IA syllabus kinda changed recently where a research into a math topic with a self defined question, i have managed to acquire discrete mathematics options textbook for it..... but i can't self study that thing because i hardly get it beyond what i needed it for and IB exams is within 2 months...... i fear so much! Oh also since you kinda like math, i tried doing some math regarding the total customizational options within warframe https://forums.warframe.com/index.php?/topic/296754-skill-tree-to-co-exist-with-modding-system-customization-mega-suggestion/#entry3380195. Not to promote the thread, but if you want to look at the third post, within each spoiler is the estimate total customization option for modding vs the possibilities of a upgrade tree. Don't look at the first two post, it is plainly words. I don't mind if you can help confirm is the maths is alright in the third post.
