Let L(t) be the instantaneous average rate of occurrences per unit time, at time t. So, for the ordinary Poisson distribution with parameter L, we just have L(t)=L for all t.    Let I be the integral of L(t) dt over a certain time interval [0,T], say.    Then, assuming that L(t) is...
The geometric distribution is: Pr(X=k) = (1-p)k-1p for k = 1, 2 , 3 ... A geometric series is a+ ar+ ar2, ... or ar+ ar2, ... Now the sum of all probability values of k = Pr(X=1) + Pr(X = 2) + Pr(X = 3) ... = p + p2+p3 ... is a geometric series with a = 1 and the value 1 subtracted from the...
In numerical analysis finding the roots of an equation requires taking an equation set to 0 and using iteration techniques to get a value for x that solves the equation. The best method to find roots of polynomials is the Newton-Raphson method, please look at the related question for how it works.
  == Answer ==   when a probability experiment is repeated a large number of times, the relative frequency probability of an outcome will approach its theoretical probability.
Error propagation in numerical analysis is just calculating the uncertainty or error of an approximation against the actual value it is trying to approximate. This error is usually shown as either an absolute error, which shows how far away the approximation is as a number value, or as a relative...
  Cos (aX) = 1 + bX, give value of X in terms of a and b.   Practical Problem at site: An arc shape insert- plate of which R was 1250 and D was 625mm and thus S = 2618 (chord length (L)= 2165), has been damaged and flattered. And site staff gives feedback that it is now D = 525 instead of 625...
The answer depends on what information you have. Given only one number, all that can be said is that the base is larger than the largest digit appearing in the number. Equations will not help if there are no "carries". For example, For example, 10 + 12 = 22 is true in any base greater than or...
This is gonna turn into a long answer, please bear with me. If you already know the algorithm's just skip to the examples. Iterative techniques for solving a linear system Ax=b, where A is a square matrix with non-zero diagonal entries, start of by first rearranging the system into a form x=Tx+c...

If the book is currently available as an online ebook in regards to a class, then one should be capable of downloading it from the virtual library in regards to the school requiring it. Otherwise, a teacher may hand it out on a flash drive at the beginning of class rather than as a download for...
Assuming a diameter of 40mm and assuming hexagonal closest packed, 625 balls would fit in a cubic foot. Boeing's website lists passenger volume for 747-400 as 31,285 plus cargo. 5536+835 = 37656 cubic feet An estimate would be the number of balls in a cubic foot times volume = 23.5 million balls....
A poisson process is a non-deterministic process where events occur continuously and independently of each other. An example of a poisson process is the radioactive decay of radionuclides. A poisson distribution is a discrete probability distribution that represents the probability of events ...
The pythagorean theorem states that a2 + b2 = c2.This means that in a right triangle, both legs squared will add up to the hypotenuse squared.To see if a triangle is a right side, add up the two legs squared and see if it equals the hypotenuse.

The rate of convergance for the bisection method is the same as it is for every other iteration method, please see the related question for more info. The actual specific 'rate' depends entirely on what your iteration equation is and will vary from problem to problem. As for the order of...
The fact that this number has been on your mind for the past six years is very likely to be a symptom of obsessive compulsive disorder. Please seek professional counseling as soon as possible, for your sake and the sake of those around you (which could be me).
The sum of the series a + ar + ar 2 + ... is a/(1 - r) for |r| < 1
It is quite complicated, and starts before Fourier. Trigonometric  series arose in problems connected with astronomy in the 1750s, and  were tackled by Euler and others. In a different context, they  arose in connection with a vibrating string (e.g. a violin string)  and solutions of the wave...
If "Jack" is "Izbj" in a code, then a likely candidate for that code is a trivial "rotate left one position" code. "Mary", in the same code, would be "Lzqx".A=Z, B=A, C=B, etc.
There are several that are especially important:    integers: ..., -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1,  2, 3, 4, 5, ...  rational numbers: ie, numbers that can be written as quotients  of integers, such as 1/2, 7/8, etc.  irrational numbers: ie, numbers that cannot be written as ...
it works exactly the same as it does with linear equations, you don't need to do any differentiation or anything fancy with this method, just have to plug in values of x, so it shouldn't make a difference if the equation is linear or nonlinear.
The number system now in commonest use worldwide is positional.  Consider a number such as 924.37. The position of each  digit in the number indicates how significant it is. The digit 9  represents 100s, the 2 10s, the 4 1s, and so on.    The Roman number, or 'numeral' system, is non...
