It's a triangle, which is the capital Greek letter delta. It's the mathematical symbol for change. It looks like this: Δ

The Edifier has it right, but darned if I can follow the notation. You really need to see this written out like a textbook to understand what's going on.\n\nClick the link below in "sources" to see the answer hosted at my website www.calculus-help.com. Right now, Yahoo! answers, as far as I can tell, doesn't allow graphics, which makes it tricky to answer ANY math questions.\n\nPlease don't post math answers, guys, if the poster knows the answer but can't get there, and you get something completely different.

in order to avoid confusion between x and the multiplication sign brackets are used for indicating multiplication

it doesnt it is a symbol meaning 10^-9

The exponent is not divided by (1 + 1) in 2*x^(1+1)/(1+1), the whole expression is. ie 2x²/2 = x². Its not to be confused with 2x^(2/2) ie 2x^1 = 2x\n\nWhen there are limits it makes no difference\n\neg ∫(from x = a to x = b) 2x dx \n= [x² + c](from x = a to x = b)\n= (b² + c) - (a² + c)\n=  b² - a² (irrespective of the value of c)

for example:\n\n-1 < 2\nthen\n1 > -2\n\nanother:\n x < -5\nthen\n-x > 5\n\n-2 x > 9\nx< -9/2\n\ns

The ∞ mean infinity.  So, it goes from -infinity to 8, not including 8 itself.  And the other one goes from 5 to infinity, including 5.\n\nThe [ ] means that you include that end point, whereas ( ) means you don't include that point.

If u're asking about boolean "v", then it represents the "OR" function. (And the "reversed v" i.e. "^" represents the "AND" function);\n\n0 v 0 = 0\n0 v 1 = 1\n1 v 0 = 1\n1 v 1 = 1

In general, it means "10 times."\n\nIn math/algebra, it means "10 times a number", but you don't know what the number is, so a letter is placed there: X.

Note: the symbol * means multiplication\n\n1/(3z+5)(2z-7)\n============\n(3z+5)(2z-7) is a short notation for (3*z+5)*(2*z-7)\n\nThis is exactly equivalent to (3*z)*(2*z-7) +(5)*(2*z-7)\nThis is exactly equivalent to 3*z*2*z +3*z*(-7) +5*2*z +5*(-7)\n\nnow lets reorganize all that:\n 3*2*z*z -3*7*z +5*2*z -5*7\nso in the end we get\n 6*z*z - 21*z +10*z -35\nwe then sum the z\n 6*z*z -11*z-35\n\nor in a more compact notation: 6z^2-11z-35\n\n2/ (2-y)(4-y)\n==========\nThis means (2-y)*(4-y)\nyou do like we did in 1/ and you get  y^2-6y+8

Either use the abbreviation sqrt(n) or use Alt-251 on your numeric keypad to get the radical sign (√).\n\nYou can also use Copy-Paste from other posts that use the symbol, so you can copy it from this answer if you like.\n\nAlso check out Start > All Programs > Accessories > System Tools > Character Map... (this all assumes you are using a Windows PC).

Use PEMDAS !!!\n\nIt stands for the order of operations:\n\nP  = Parenthesis\nE  = Exponents\nMD = Multiplication and Division\nAS = Add and Subtract.

x' € S - {x}\nworks fine...\n( replace the € by the usual "is an element of" symbol )
