math question for tipsy the mathematician

can you explain, in simple terms, the differenece between imaginary & complex numbers to me

you can post here or PMme, thank you

tomoko this is for you

ok then, sorry tipsy

its really late here, so im too tired to remember the math persons name

to be fair tipsy is also going into college right now since im pretty sure she's 19 but i dont know if she'd know the answer to this

im only interesed in math/physics/EE people, im sorry though

A complex number is simply any number that contains real AND imaginary parts - 3 is a real number, 2i is an imaginary number, and the quantity 2i - 3 is a complex number - they take the form a + bi (or bj, or jb if you're an electrical engineer) where a and b are real numbers and i/j is imaginary

i think the best way to explain the difference is that complex numbers are guaranteed to be infinite. so basically, they have real (integers) and imaginary (i, where 0 = 0i) pieces. so "i + 7" is a complex number

suppose if you have your x and y axis and a z axis. keep adding sets, or fake lines, like a j or k axis, which means you are adding more dimensions. that number has 5 parts now, three of which are real (x and y and z axis). you go on and on, adding more fake axises

it even works out when dealing with transcendental numbers (non algebraic)

i fucking remember learning this

but i forgot wtf it was

sorry flade

have not done math in 2 years

imaginary and complex numbers? easy shit, learned it on my own right after multiplication. chyeah.

yeah what tomoko said

holy fuck my engineering class is so goddamn easy its like basic algebra

i havent found a lot of uses of math when making robots

i was going to do some differentials work to approximate the correct volume of a thing i did for calculus bc but then i realized the difference in volume was too small to show

my favorite tool for taking measurements is this ancient set of calipers made from REAL AMERICAN STEEL that my grandpappy used
