Thank you so much! That makes so much more sense then what I was trying to do! Is there a way for me to rate your response as AWESOME!

My questions I am looking at is: We have twelve balls, four of which are white and eight are black. Three blindfolded players, A, B, and C draw a ball in turn, first A, then B, then C. The winner is the one who first draws a white ball. Assuming that each black ball is replaced after being...

My summation as well as the integral is supposed to represent the area under the curve. n and p are just positive integers. I need to figure out how the area under the curve can be written as the integral equal to the summation.

f I consider the area of the family of curves as y = (1 - x^1/p)^n where x is greater than or equal to zero but less than or equal to one, I can write that in as integral as the integral from 0 to 1 of (1 - x^1/p)^n dx but I'm not sure how to write that as a summation, which I have been...

Nevermind, I figured it out...I was actually subtracting out an equation from earlier in the problem.

I'm looking at an example of a problem in my book and one line says (y - a)^2 = p(x - e) and then it says by subtracting they get 2ay - a^2 = pe I'm not seeing what they subtracted to get that... Please help me! Nicole

How would you go about finding the power series for sqrt(x+1) by applying the square root algorithm. I can do it using binomial expansion and other formulas but I'm not familiar with the square root algorithm involving variables.

So the Haversine formula states that cos(c) = cos(a)cos(b) + sin(a)sin(b)sin(C) I for all of this formula all I really know is C for each formula. So if I have 50 degrees, do I write that the side opposite of that is: cos(50) = (cos(a)cos(b) - cos(c))/(sin(a)sin(b)) I don't see how I...

Thanks so much for a response! Girards formula gives me formulas for the area of a spherical triangle. Do I have to find the area in order to find the length of the sides? Do you know where I can see examples of solved problems like this. I can't find a single one.

I need some help with spherical triangles. I am looking for the lengths of the sides of a spherical triangle given that all the angles. One being 90 degrees and the other 2 angles being 50 and 70 degrees. I don't even know how to go about solving this. I know there are 4 formulas for solving...

I'm sorry, but I dont' understand why you're just looking at Z(cuberoot 3) instead of the whole equation? Is the x+y(cuberoot of 3) part of the equation irrelevant? Please help me understand!

I think I might have phrased this question wrong, but I figured it out. THANKS

I'm looking at a card shuffle. And in shuffle would be the permutation (1, 2, 3, ..., n, n+1, n+2, n+3, ...2n) to (2, 4, 6, ..., 2n 1, 3, 5, ...2n-1) I know that it would take 52 perfect shuffles to get the deck of cards back in the original order. I think that I'm supposed to show this using...

I don't understand how to factor a polynomial over Z3 [x], Z7 [x], and Z11 [x] I need to factor the polynomail x3 - 23x2 - 97x + 291 PLEASE HELP!

So to show S was a subring of (R , + , .) I used the more precise version I talked about in my last post: So, = 0 is in S and so, S is a non empty subset of R Therefore, S is a subring of R. Now condition 2: Let say, x1+y1(cuberoot 3) + z1(cuberoot 9), x2+y2(cuberoot 3) +...
