Imaginary Numbers in Math

[-J�ker-]

math class in when i eat lunch..... what the heck are you guys talking about!!!!

i am actually smarter than my math teacher in a sense...

i asked her what "i" equaled,and she had no idea what i was talking about...

she can never answer my questions...

heres some irrellavent material.

In form a+bi, the a is the X value, and the bi is the Y value. I just had a test on these in school. I hate regents math. Only a few states have the Board of Regents. NY, Cali, and i think there is one more.

Now, the regents is being called the Advanced Regents Diploma, and the Local is being called the Regents. Pretty crappy.. Im going for Adavanced regents of course

In a sense, i doesnt equal any thing, it is imaginary. But to relate it to a number, it is the {-sqaure Root} of a number. for example.

{will represent every thing underneat the radical.}

{-32}
{i}{16}{2}
4i{2}

im pretty sure thats how it works,

Complex numbers are VERY important... many many engineering related applications among other things.

Hyperbolic functions (like sinh, cosh... etc.) have 'i' built in, you just don't see it. But you can mathematically convert parabolic functions to hyperbolic with complex numbers.

When you're dealing with electrical circuits and such, you use complex numbers in your formulas to figure out what the circuit is putting out.

Polar coordinate system has a 'real' part and an 'imaginary' part if you ever looked into it.

It is not 'imaginary' in the sense that it is 'fake'. It is not fake, it just is in a category different from 'real' numbers.

LoL, I haven't touched imaginary numbers since college.

It can't exist, my calculator clearly states error when I punch in a negative root. My calculator doesn't lie to me, and it only shows me actual numbers. For those wondering, I'm currently sitting at 97% in Alg 2 as a sophomore.
