They are extremely useful to solve real life problems.

By greatly simplifying otherwise complicated problems that don't originally involve imaginary numbers. A HUGE shortcut in some problems. Never heard of phasors? Never heard of expanding a problem to the complex plane? Thought not.

I just recently started AP AB Cal, but if I'm not mistaken, it would also be much harder, or even impossible, for us to make electronics. Some calculations to make that cicrutry come from imaginary numbers.

Not impossible, but much harder indeed. Not only the notation is greatly simplified with the use of "i" but also it is much easier to work with complex impedances instead of differential equations to solve circuits.

....Mind ****** hows it 2i? i = square root -1 so, square root -4 wouldn't it equal 4i?

i stands for imaginary which is the square root of negative one.. u learn it in like 8th grade..

exactly, so its 4i.... i stands for sq root -1, because its imaginary you cannot take the square root of it, sq root -4 is imaginary so 4i

square root of 4 is 2 >.> so when u take that is 2i

take algebra 2. you will learn about the square root of -1, which is i. so if i stands for the sq.rt. of -1, then it makes 2i. what are you, 10?

already took it.... which is why i understand it. you cant take the square root of -4 so its not 2i. square root of 4 is 2, you cant do -4

Ok I'll Try and explain this,
the square root of -1 is i yes
but the square root of 4 is 2
2i means 2 times the square root of -1
so if you square 2i you get -4
It's how to explain using logic.

what i've learned is **** Imaginary stuff, i understand that you have to learn Real stuff, but why imaginary?? :(

Why imaginary?
Look at a graph.
If you go westwards 4 and southwards 4 you are at (-4,-4).
Then you are asked to square root both sides
On technicality you would square root -4 both
That would give you a wrong answer cause square rooting a negative number.
So they give you the 2i for both, although it would be wrong
You would know that though for it being imaginary
So you would see both sides lengths are actually 4
Even though it says -4 on the graphing point.
So you would square root your 4's for a length of 2
Which would give you the point of (-2,-2)

And Thank You Pre-Cal and My Teacher for me to learn this.

Oh ho ho its funny because because i stands for imaginary number and the personal pronoun! Oh ho ho.
