Please only ask one question at a time - you are asking three separate questions here. –  Matt E. Эллен Sep 24 '11 at 20:59
Also, can you add some context to this request? These characters are not used in normal English writing. –  Matt E. Эллен Sep 24 '11 at 21:06
@Hugo: It's actually three single word requests. I see nothing wrong with it other than that it is three questions in one. –  Daniel Sep 24 '11 at 21:13
Although it is difficult to enter symbols like these in Google or other search engines, you can often search for them in references like Wikipedia; they return the pages @drɱ65 δ has mentioned in the answer below. –  aedia λ Sep 24 '11 at 21:21
I don't understand the votes to close. We're always getting questions like "What's the word for [ddescription of something]?". This one is as good as it gets! @Gimp has actually given us the exact somethings he wants the names of. No need to keep asking for clarification about exactly what his "something" is! –  FumbleFingers Sep 25 '11 at 1:24

~ is a tilde.

^ is a caret.

 is a grave accent when used as an accent or a backtick, when used alone.

I've heard ~ (tilde) referred to as wiggle and twiddle in numerous math lectures. Ordinarily, a given lecturer only uses one term or the other and is consistent. The common word for ^ (caret) in math lectures is hat and in LaTex it's obtained by \hat. –  jwpat7 Sep 24 '11 at 21:25
@jwpat7: Good grief! - wiggle, twiddle, hat?. I suppose those maths teachers were too busy learning numbers to learn letters. –  FumbleFingers Sep 25 '11 at 1:30
@fum, none of those are 'letters' –  whoabackoff Oct 6 '11 at 16:05
@whoabackoff: True, but I'd still classify such teachers as "unlettered", even though I've no doubt they'd all at least know the alphabet. I find it particularly depressing that jwpat7's reference to "math lectures" implies we're talking about reasonably advanced maths teaching here, where tildes and carets are common symbols. –  FumbleFingers Oct 7 '11 at 16:25
@fum, it's not uncommon for symbols to go by different names in mathematics: exclamation mark for factorials, slash for division, colon for ratios, full stops for decimal points... even symbols like the asterisk and number signs go by different names in math. I find this in no way depressing, and would never classify these professors as "unlettered". –  whoabackoff Oct 7 '11 at 18:02
• ~ - this is a tilde
• ^ - this is a caret
