It's not that hard.

A dude 100s of years ago named Pythagoras proved that you could determine the length of a side of a triangle as long as you knew the other two side lengths with a simple formula:

a^2 = b^2 + c^2

In this case, we know side a is x, side b is 3 and side c is 4. So subbing in we get

x^2 = 3^2 +4^2
x^2 = 9+16
x^2= 25

To make x^2 into x you take the squareroot. But what you do to one side must be done to the other

Sqrt(x^2) = sqrt(25)
x=5

Don't be mean.

Anyone wanting to learn higher level stuff, just ask.

I don't think anyone is ready for that just yet

We did imaginary numbers, polar co-ordinates and integrals of trig functions in my final year of school

I think Millky95 is ready. I would like to take him as my Padawan.

Oh buddy that's just the beginning.

Sadly, I don't remember as much as I would have liked. I took the hard maths for fun

Not enough surds.

 

[miss_kate18]

You're all reminding me why I dropped Maths after Year 10.

 

[miss_kate18]

Why? Just cos

 

[Millky95]

Why? Just cos

I feel like this is incorrect though

 

[Loonerty]

Yeah, the s**t is already real there. Or if it's imaginary, then it's still imaginary.

 

[Millky95]

Yeah, the s**t is already real there. Or if it's imaginary, then it's still imaginary.

-s**t is real, sqrt(-s**t) isn't real. I guess by squaring it, it becomes real again.

 

[Loonerty]

-s**t is real, sqrt(-s**t) isn't real. I guess by squaring it, it becomes real again.

But sqrt(-s**t) =/= s**t
Squaring it doesn't make s**t real.

 

[Millky95]

But sqrt(-s**t) =/= s**t
Squaring it doesn't make s**t real.

-s**t is still real as long as s,h,i,t =/= an imaginary number or 3 of them aren't imaginary. The negative shouldn't matter. You're probably right though

Yeah but the squaring isn't what is making s**t real, s**t is always real there.

I'm being pretty pedantic.

"In math you are either right or wrong. No close, no really got it, no almost. Correct or wrong"
- A Math teacher I had

Paraphrasing obviously

Multiplying s**t by i would make s**t real, if s**t was imaginary.

Hmm but then you're redefining what s**t is.

That's why I did three English subjects at Year 12 and no Maths. In English being a great BS artist gets you top marks.

But it still makes it real though?

What pissed me off was how it was supposed to be like that, but I'd have slightly controversial stance or a difference to the norm and get punished for it no matter how much evidence I provided from texts

 

[Loonerty]

I suppose you're right, yeah.

but I'd have slightly controversial stance or a difference to the norm and get punished for it no matter how much evidence I provided from texts

My experience with English was that if your opinion didn't line up with the marker's, unlucky, you lose marks.
