Nov 23, 16 · See below Symmetry f(x) = e^((x)^2) = e^(x^2) = f(x) So the function is even and the graph of the function is symmetric with respect to the yaxis Increase/Decrease and Extrema f'(x) = 2xe^(x^2) Since e^"real number" is always positive, the sign of f' is the opposite of the sign of x So f is increasing on (oo,0), has local maximum f(0) = 1 and then f decreases on.

(Leting g(x) = xn yields moments for example) Finally, the variance of X is denoted by Var(X), defined by E{X − E(X)2}, and can be computed via Var(X) = E(X2)−E2(X), (2) the second moment minus the square of the first moment We usually denote the variance by σ2 = Var(X) and when necessary (to avoid confusion) include X as a subscript.

One way to solve this is based on recognizing that the left side is sinh(x) which makes your equation sinh(x) = 2 (If you have never heard of sinh (hyperbolic sine), then skip down to "Without sinh" below).

Proof lnexy = xy = lnex lney = ln(ex ·ey) Since lnx is onetoone, then exy = ex ·ey 1 = e0 = ex(−x) = ex ·e−x ⇒ e−x = 1 ex ex−y = ex(−y) = ex ·e−y = ex · 1 ey ex ey • For r = m ∈ N, emx = e z }m { x···x = z }m { ex ···ex = (ex)m • For r = 1 n, n ∈ N and n 6= 0, ex = e n n x = e 1 nx n ⇒ e n x = (ex) 1 • For r rational, let r = m n, m, n ∈ N. E x ex 2 Begin by dividing the denominator into the numerator (or, more easily, rewrite the top as e x ex 2 ex 2), and you get You can learn a great deal about the graph of the function without using calculus, by just examining the form of the function f(0) = 1 The graph lies in the strip between y = 0 and y = 1. No Let’s look at numbers you are more familiar with Try 2^3^2 This is 2^9, which is 512 Now let’s try (2^3)^2 The parentheses tell us to first raise 2 to the third power That’s 8 Now you have 8^2, which is 64 Same issue occurs when the bas.

If so, where do I go from there?. Markov's inequality If X is Proof Let I be the indicator random variable that is 1 when X >= , so EI = P( I = 1 ) = P( X >= a). 12 Prove that a set of vectors is linearly dependent if and only if at least one vector in the set is a linear combination of the others 13 Let A be a m×n matrix Prove that if both the set of rows of A and the set of columns of A form linearly independent sets, then A must be square Solution Let r1;;rm ∈ Rn be the rows of A and let c1;;cn ∈ Rm be the columns of A.

Values The Qfunction is well tabulated and can be computed directly in most of the mathematical software packages such as R and those available in Python, MATLAB and MathematicaSome values of the Qfunction are given below for reference. Note that the denominator vanishes only if t = e(x t)2, and (x t)2 0, so the denominator can only vanish if t 1 In particular, u is a C 1 , indeed C 1 , function.
