14. DERIVATIVES OF LOGARITHMIC AND EXPONENTIAL FUNCTIONS. The derivative of ln x. The derivative of e with a functional exponent. The derivative of ln u(). The general power rule. T HE SYSTEM OF NATURAL LOGARITHMS has the number called e as it base; it is the system we use in all theoretical work.

If X 1 is determined by Y (e.g., is a function of Y; X 1 = g(Y)), then E(X 1X 2jY) = X 1E(X 2jY). The idea here is that since we are treating Y as a constant, and since X 1 is determined by Y it too can be treated as a constant. A special case is E(XYjY) = YE(XjY). 2 12. The Variance of . X. The quantity .

For instance, e x can be defined as → ∞ (+). How do you Use implicit differentiation to find the equation of the tangent line to the curve 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.

10. Using the same wavefunction, Ψ (x,y), given in exercise 9 show that the expectation value of p x vanishes. 11. Calculate the expectation value of the x 2 operator for the first two states of the harmonic oscillator.

The parser is implemented in JavaScript, based on the Shunting-yard algorithm, and can run directly in the browser. E(Y) = Sum(y P(Y = y)) where P(Y = y) is the probability that the random variable Y takes on the value y, and the sum extends over all possible y. In a similar fashion E(X + Y) = Sum(z P(X + Y = z)) where the sum extends over all possible values of z.

A special case is E(XYjY) = YE(XjY). 2 12. The Variance of . X. The quantity . h (X) = (X – μ) 2 .

y = k I have an equation I need to solve by using undetermined coefficients: y'' - y' = ex The auxiliary equation is: r2- r = 0 , so 2 real roots (R1=0, R2 = 1) So, yc(x) = C1 + C2ex Now for the particular solution: I can try Aex but this is already present in the complementary E(X + Y) = Sum(zP(X + Y = z)) where the sum extends over all possible values of z. Thus you are looking at all possible combinations of values of X and Y that add to z. This is why you needed to "add each item from X to each item from Y" when verifying that E(X + Y) = E(X) + E(Y). integrate x/(x-1) integrate x sin(x^2) integrate x sqrt(1-sqrt(x)) integrate x/(x+1)^3 from 0 to infinity; integrate 1/(cos(x)+2) from 0 to 2pi; integrate x^2 sin y dx dy, x=0 to 1, y=0 to pi; View more examples » Access instant learning tools.

Expectation of a constant = the constant E( X ) - u2 X 2 (e.g. P(Y = yjX= x)) Independence for r:v:’s Xand Y This is a good time to refresh your memory on double-integration. We will be using this skill in the upcom- For example, suppose X is a discrete random variable with values x i and corresponding probabilities p i. Now consider a weightless rod on which are placed weights, at locations x i along the rod and having masses p i (whose sum is one). The point at which the rod balances is E[X]. Find dy/dx e^(x/y)=x-y. Differentiate both sides of the equation.
