Yeah I reworded that last bit when I realized that I was asking about the rules governing manipulation of complex numbers (which I've covered before in previous courses) instead of the method of treating complex numbers as coordinates rather than a+bi. I'd never seen 'i' treated in that fashion...
Aheh, this answer is closer to what I was looking for, although I suspect I should've asked this question on a programming forum rather than a mathematics subforum! Since asking this question I indeed have wondered how the calculator represents real numbers, although I have a conceptual grasp of...
At risk of butting into a conversation not my own just to satisfy my own curiosity.. wouldn't the above statement be true for ALL triangles existing on a sphere? Including the "infinitesimally small triangle" that DaveC~ mentioned on the 'outside' of your 900~ degree triangle. On an infinite...
Ahhhh you're right. :blushing: When I took the natural log I removed the e and left the ln; I forgot to mentally remove the ln after I applied one of the log properties. Fail.
Ah see, I didn't know that. ;)
I suppose I'll have to wait for Calc II then. Hell the whole idea of a complex...
@Micromass: Just to be clear I'm not at ALL saying the mainstream is wrong and I'm right. I recognize that I'm wrong and that the way I'm seeing it is incorrect, so I was hoping to have my view corrected. ;) But to elaborate on my confusion, to get from 23.1~ to -1, something is being done...
Like many math newbies, complex numbers (or at least the idea of complex numbers) are a source of some confusion... but I've worked with them before and I'm reading through posts on PF that I hope will give me some sense of intuition about them. That said, there is one nagging question that I've...
I don't have access to your book, so it's entirely possible that I'm misreading the question... but I'll try to help out anyway, and hopefully not create further confusion.
a(b+c) = ab + ac
The distributive law isn't as bad as it might look. Sometimes the variables can mess with my head a bit...
