In probability theory, the conditional expectation, conditional expected value, or conditional mean of a random variable is its expected value – the value it would take “on average” over an arbitrarily large number of occurrences – given that a certain set of "conditions" is known to occur. E[X2jY = y] = 1 25 (y 1)2 + 4 25 (y 1) Thus E[X2jY] = 1 25 (Y 1)2 + 4 25 (Y 1) = 1 25 (Y2 +2Y 3) Once again, E[X2jY] is a function of Y. Intuition: E[XjY] is the function of Y that bests approximates X. This is a vague statement since we have not said what \best" means. We consider two extreme cases. First suppose that X is itself a function of Nov 17, 2018 · Solve the differential equation dy/dx + 1 = e^x+y . asked Sep 21, 2020 in Differential Equations by Chandan01 (51.2k points) differential equations; class-12; 0 Nov 15, 2016 · y = -ln(-e^x + C) , or ln(1/(C-e^x)) dy/dx = e^(x+y) :.

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

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!

Then the base b logarithm of x is equal to y: log b (x) = y. For example when: 2 4 = 16. Then. log 2 (16) = 4. Logarithm as inverse function of exponential function.

25. · First of all I think that, maybe, there is a little mistake in your writing. Doesn't the function is: x = e^t-1 y=e^(2t) instead of yours? If I am right, than: x+1=e^trArrt=ln(x-1) and y=e^(2ln(x+1))rArry=e^ln((x+1)^2)rArry=(x+1)^2 (this is because: e^lnf(x)=f(x)) And this is the equation of a parabola centered in V(-1,0) and that passes from the points (0,+1), as you can see: graph{(x+1)^2 2016. 9. 12.
