whats the symbol that looks like an E but is round. it looks like the end of a pitchfork (turned on its side, open side facing the right like an upper case E). like a left parentheses but with prongs. is it approximates? or something like that? i'm reading lecture notes and i totally forgot.

scroll down to greek small letter epsilon

1. upside down A means "for all"

2. backward E means "there exists"

3. epsilon (looks like c with horizontal line in middle)
means "an element of" or "in" of "belongs to"

4. backwards epsilon
means "such that"

5. three dots triangle, point up
means "therefore" or "thus"

6. three dots triangle, point down
means "because" or "due to"

Yep. For example tE(0,2pi) means t belongs to the domain 0 to 2pi
