Pi is a name given to the ratio of the circumference of a circle to the diameter. That means, for any circle, you can divide the circumference (the distance around the circle) by the diameter and always get exactly the same number. It doesn't matter how big or small the circle is, Pi remains the same. Pi is often written using the symbol  and is pronounced "pie", just like the dessert.

I see too many combinations to make anything out easily.\nI thought maybe the first might be PR, could also be AXIO...(didn't quite make AXIS POWERS, too bad!)  All those dots in a row have me stumped.  Letters using only dots: e (1 dot), i (2 dots), s (3 dots) and h (4 dots), as well as the number 5 (5 dots).\nAny clues?

Pi is the ratio of the circumferance of a circle to its diameter.  The following equation is for the area of a circle:    A = pi*r^2\n\nThe Math Forum website has a very complete and east-to-understand explanation.

It's a food, typically with a crust and some good stuff in the middle.\n\nIf you mean pi, then it's the ratio of the circumference of a circle to its diameter.  Its value is approximately 3.14.

Rx is the symbol that originated in medical prescriptions. "℞" (also written as "Rx") and "medical prescription" are sometimes used interchangeably. The use of ℞ in prescriptions originated as an astrological symbol that was written for talismanic reasons at the start of medical prescriptions. Later it changed into ℞ (an uppercase R with its tail crossed), and was used as an abbreviation for the Latin word recipe = "take" (imperative), i.e. an instruction to the pharmacist to take the items listed in order to prepare the medicine. When printing came, it was rendered as "Rx"

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

we don't use k,l,m,n anymore. The letters are s,p,d and f. They refer to the different shapes of the shells(orbitals)

The R's mean that you can write data only once, and from begining to end. That basically means that if you want to write data again on the cd, you will have to reformat it, which means that u will have to erase all the stuff on it first.\n\nThe Rw's mean that you can burn a disc, then go back and add or insert data in it without acutally having to delete evrything on their previously\n\nthe + and - symbols indicate the type of formatting, the most common supported form is the '-' symbol, however many programs (including microsoft, apple, nullsoft, and megapixis) support the '+' formatting. In all honestly the formatiing shouldnt even matter, as most if not companies try to support as many as possible.

It's a circle of radius 4, centered at the origin.\n\nThe equation of a circle centered at (a, b) is:\n\n(x - a)² + (y - b)² = R²\n\nWhen the circle is centered at the origin, (a, b) = (0, 0), or:\n\nx² + y² = R²\n\nTherefore, y is simply given as:\n\ny = ±sqrt( R² - x² )\n\nIn this case, R² = 16, so R = 4. The plot you want to make is one such that every point on the plot is 4 units away from the origin.

No, there is not. Circle is part of called Conic Graphs.\nA circle can be described as all points that are at the same distance (radius) of a fixed point (center). You can not give this kind of description about a triangle or square.\nNow, the truth is that you can describe -for example- an square with four lines (y=a , y=b, x=a, x=b)but you can not put everything in a single equation, besides this, this kind of lines are infinites (y=a from -inf to inf).\nThere are other kind of equations that gives you the area or perimeter of these shapes (i.e: b*h/2), but this is not what you're looking for.\nSo, again: There are NO equation of a triangle.
