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 continuous, or maybe...

The geometric distribution is: Pr(X=k)=(1-p) k-1 p for k=1, 2 , 3 ... A geometric series is a+ ar+ ar 2 , ... or ar+ ar 2 , ... Now the sum of all probability values of k=Pr(X=1) + Pr(X=2) + Pr(X=3) ...=p + p 2 +p 3 ... is a geometric series with a=1 and the value 1...

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.

x + y + x=2x + y

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...

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...

34.872 rounded and chopped to 1 sig fig is 30. The previous answer 34.8 is wrong, 34.8 is 34.872 chopped to 3 sig figs. Any digit in a number that is not zero is classed as a significant figure e.g. your number above has 5 sig figs but if it was 30.072 it would only have 3 sig figs: 3, 7 and 2....

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 A x=b, where A is a square matrix with non-zero diagonal entries, start of by first rearranging the system into a form x ...

A number is divisible by another when the remainder of the division is zero.

A Taylor expansion is a way of representing a function in terms ofa sum of its derivatives. Please see the link.

Since the questioner didn't specify which shooting method was being used, I'll explain the linear shooting method. First off, the shooting method is used to solve boundary-value problems, or BVPs, where instead of being given 2 initial conditions to solve a problem, we only have the value of the...

Truncation error is the error introduced when an series is shortened, i.e. "truncated", before it is complete. For instance, 1/3 is 0.333333333...etc., but we place limits on how many decimal digits to use, so that introduces an error. Another example is a large number, such as 2 40 -1. That...

h, being the step size of an algorithm in numerical analysis, is always (b-a)/N where x is in the interval [a, b] and N is the number of iterations in the algorithm.

It is the study of algorithms that use numerical values for the problems of continuous mathematics.

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...

2.5 or 5 over 2

Is the binomial expansion.

I would have thought this blindingly obvious but no matter, a lower percentage error is better because it means your approximation to a solution is closer to the real answer than an approximation with a higher error.

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 ...

It is quite complicated, and starts before Fourier. Trigonometricseries arose in problems connected with astronomy in the 1750s, andwere tackled by Euler and others. In a different context, theyarose in connection with a vibrating string (e.g. a violin string)and solutions of the wave equation. ...

No, not all adherent points are accumulation points. But all accumulation points are adherent points.

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.

the missing space between the 5 and 6. what is so impossible about that? are you just trying to be ironic, funny?

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 eachdigit in the number indicates how significant it is. The digit 9represents 100s, the 2 10s, the 4 1s, and so on. The Roman number, or 'numeral' system, is non-positional. The...

Answer .I don't know why there should be 4 laws (=axioms) specifically. In mathematics you can choose whatever system of axioms and laws and work your way with those. Even "logic" (propositional calculus) can be redefined in meaningful ways. the most commonly used system is Zermolo-Fraenkel...

"Convergence in probability" is a technical term in relation to a series of random variables. Not clear whether this was your question though, I suggest providing more context.

Poisson distribution shows the probability of a given number ofevents occurring in a fixed interval of time.

In integer division, you expect the result to be an integer. Anything left over will be quoted as a remainder. The more commonly used division (not integer division) will continue calculating decimals, up to the desired accuracy.

The moment generating function is M(t)=Expected value of e^(xt)=SUM[e^(xt)f(x)] and for the Poisson distribution with mean a inf=SUM[e^(xt).a^x.e^(-a)/x!] x=0 inf=e^(-a).SUM[(ae^t)^x/x!] x=0=e^(-a).e^(ae^t)=e^[a(e^t -1)]

A normal distribution with a mean of 65 and a standard deviation of 2.5 would have 95% of the population being between 60 and 70, i.e. +/- two standard deviations.

No it is a "discrete" distribution because the outcomes can only be integers.

It could be divergent eg 1+1+1+1+... Or, it could be oscillating eg 1-1+1-1+ ... So there is no definition for a sequence that is not convergent except non-convergent.

Error is the term for the amount of difference between a value and it's approximation, and is represented by either an upper or lower case epsilon (E or Îµ) E abs , absolute error, is |x-x*| where x* is the approximate of x, and gives a value that shows how far away the approximate is as a...
