Math Symbols

I put a few maths symbols in the description up top. You should be able to drag your mouse across one, then copy and paste it into the post like this:

√4 = 2

2 ≠ 3

2² = 4

³√(27) = 3

ƒ(x) = x³

θ = 20°


Hope this looks and works fine for everyone.

Re: Math Symbols

So, ryudo, what are you studying in math at the moment?

I have to go now, but if you reply here, I will see it later and reply to you - so be sure to check back in a day or so.

Bye for now.

Re: Math Symbols

That is amazingly useful.

∫3x² dx=x³+c

Sorry, felt like trying it out...

Why did the vector cross the road?
It wanted to be normal.

Re: Math Symbols

2 ÷ 1 = 2
½ × 2 = 1
θ = theta (I think)


Oh, no! What does this one mean? ±

Re: Math Symbols

√4=±2.
Because 2² and (-2)² both=4

θ is indeed a greek letter called theta, usually used in maths for angles.

Re: Math Symbols

Theta drags. Omega is the best greek letter.

Re: Math Symbols

We obviously can't forget Pi, Phi and Psi.
