Q. Is there another way to write x^-2/3?
Asked by straydawgzdd - Sat May 10 04:09:08 2008 - - 4 Answers - 0 Comments
A. Parenthesis would help but: (x^-2)/3=1/(3x^2) If you meant x^(-2/3) then: x^(-2/3)=1/(x^(2/3))

What is the mathematical notation for "Relative To"?
Q. Such as three dots representing therefor, an equal sign representing is, or an equal sign with a line going through it representing is not/cannot be. What is the symbol for "Relative To" as in A is relative to B?

A. The colon, as in A:B which means A is to B, or A relative to B.

Q. { (1/n): n is in N (The set of Natural Numbers) } I couldn't type this well here. This is from my Intermediate Analysis class... and I need some help! My guess was the set is just {1} (not sure if I'm right!)... because all the other elements are less than or equal to one, and greater than zero, and they can't belong in the subset of the naturals.

Q. Here's a description: two large parentheses with 2 numbers inside, one on top of the other. There is no division line. In my problem, it's a 30 over a 10, all in parentheses. Somehow, this equals to 41801760, or 3^2 * 5 * 7 * 11 * 13 *32 * 29

A. An equivalent notation is nCr or C(n, r), n being your top number and r being the bottom number. It is equal to n!/[r!(n-r)!] and is the number of combinations of r objects you can create by picking from a pool of n, given that order does not matter.

What does this mathematical notation mean? (variable directly under min/max)?
Q. If I have the equation M(j) = min {M(j - v sub i)} + 1 , and imagine there is an i written directly under the min, what does this mean?
Asked by esimonds03 - Mon Jun 16 20:23:25 2008 - - 1 Answers - 0 Comments
A. That means that the minimum is taken over all possible values of i, as j is a fixed quantity. That is, for any given j, find M(j - v(i)) for all valid i, and the minimum of those quantities is defined to be min_i {M(j - v(i))}. e.g. min_(i > -1) {i + 1} = 1, with i = 0 giving said minimum value. Hope this helps.

What does the mathematical notation "cis" stand for?
Q. e.g. not sure what 8cis(180) means
Asked by groovybaby33 - Thu Apr 24 09:58:07 2008 - - 6 Answers - 0 Comments
A. Its not all that a popular notation but cis t is short for (cos t + i sin t), making cis t = e^it by Euler's relation. Its just convenient when introducing the polar form of a complex number without the exponential form since its shorter to write. 8 cis (180) means (assuming 180 is degrees, but when dealing with complex numbers or any higher mathematics onward from that it is better to use radian measure. This becomes pi radians) 8 cis (pi) = 8. e^i.pi = 8. (cos pi + i sin pi) = -8

A. Mathematical objects are logical construct with its existence in the platonian world of logics. A lot of times, they can be adopted to fit things in our world. For example, this mathematical object called Group. Do they "exist"? mathematically, yes, they do. They are a set of logical and consistent axioms so logically they can exist. Instead of asking if some mathematical object exists, maybe it's more meaning ful to ask if anything in this real world fit the properties of such object. For example, a mathematical object called Group. In physical science, economics or any field, as long as u find something that u can map one to one the properties with a Group, these things are group and have all the logical consequences of Groups. Numbers… [cont.]
