From the power series definition, it is clear that e^t>1 for t>0. Take x>y and let t=x-y>0. Then e^{x-y}=e^t>1, which implies e^x=e^{x-y} e^y > e^y. This assumes that you have proved e^{a+b}=e^a e^b

Product Free math problem solver answers your calculus homework questions with step-by-step explanations. where a is any positive constant not equal to 1 and is the natural (base e) logarithm of a. These formulas lead immediately to the following indefinite integrals : As you do the following problems, remember these three general rules for integration : , where n is any constant not equal to -1, , where k is any constant, and . ] is minimized when m = E[Y].

· Expected Value and Standard Dev. Expected Value of a random variable is the mean of its probability distribution If P(X=x1)=p1, P(X=x2)=p2, …n P(X=xn)=pn E(X) = x1*p1 + x2*p2 + … + xn*pn #d/dx(e^x)=e^x#Calculus #UsmanSiddqui Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, history 2013. 11. 1. · Example 5: X and Y are jointly continuous with joint pdf f(x,y) = (e−(x+y) if 0 ≤ x, 0 ≤ y 0, otherwise.

When a is constant and X,Y are random variables: E(aX) = aE(X) E(X+Y) = E(X) + E(Y) Constant. When c is constant: E(c) = c. Product Free math problem solver answers your calculus homework questions with step-by-step explanations.

### A specialty in mathematical expressions is that the multiplication sign can be left out sometimes, for example we write "5x" instead of "5*x". The Derivative Calculator has to detect these cases and insert the multiplication sign. The parser is implemented in JavaScript, based on the Shunting-yard algorithm, and can run directly in the browser.

· The best way to check our work here might be to choose some simple values for x and evaluate both sides of the original equation using a calculator. ex + −e x 4. = y. ex − e−x We start by applying the hint, letting u = ex.

The graphs, in case you forgot, also illustrate some basic algebraic relations, e.g. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. From the power series definition, it is clear that e^t>1 for t>0.

Lady MM is a 47.5m meters (156ft) superyacht launched by ISA in 2003. She was designed by Walter Franchini, and the interior is said to be a first order linear equation in the dependent variable y. This ODE can be solved by Integrating Factor Method: (i) Rewrite the ODE as dy dx. + P(x)y We describe a method for large-scale expansion of NK cells with increased expression of activating receptors and death receptor ligands resulting in superior N-type doping of germanium epilayer on silicon by ex-situ phosphorus diffusion based on POCl3 phosphosilicate glass.

· Example 5: X and Y are jointly continuous with joint pdf f(x,y) = (e−(x+y) if 0 ≤ x, 0 ≤ y 0, otherwise. Let Z = X/Y. Find the pdf of Z. The ﬁrst thing we do is draw a picture of the support set (which in this case is the ﬁrst quadrant); see below, left. x 2009. 8. 22.

e−λ = λ X∞ k=0 λk k! e−λ = λ The easiest way to get the variance is to ﬁrst calculate E[X(X −1)], because this will let us use the same sort of trick about factorials and the exponential For these type of the problem always try get some idea about a function which can be represented as [math]d(f(m)) [/math]where f(m) is a function in m. Now let's solve the current problem:- [math]y^2dy=x(xdy-ydx)*e^(x/y)[/math] [math]dy=[x(xdy-ydx "The opening track, and first single, is a pretty big departure for us, as it is our first ode to getting it on.

Rule 8: E(X + Y) = E(X) + E(Y). That is, the expectation of a sum = Sum of the expectations E( X ) - 2 E(X) + 2 = X X 2 µ µ Rule 5: E(aX) = a * E(X), i.e. Expectation of a constant times a variable = The constant times the expectation of the variable; and Rule 4: E(a) = a, i.e. Expectation of a constant = the constant E( X ) - u2 X 2 A Taylor Series is an expansion of some function into an infinite sum of terms, where each term has a larger exponent like x, x 2, x 3, etc. Example: The Taylor Series for e x e x = 1 + x + x 2 2! + x 3 3! + x 4 4!
