Can someone explain this and/or give an example? E is the symbol for "sum of"  Introducing ex. Gilbert Strang.

### 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

Recall that any number or variable when raised to the 0 power is 1. In this case if b or x is 0 then, e^0 = 1.

• Wehave f0(x) = e−x Oct 07, 2009 · e^(x/y) = x - y. On the left we will need to combine the Power and Chain Rules. (1/y)e^(x/y) dx - xe^(x/y) dy = dx - dy. Now combine the dx and dy terms. Dividing both sides by . Differentiating both sides with respect to x, Dividing both sides with .

y = ln x are easily pictured, too; below the y = ln x and the y = ln (1/x) functions are shown. 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. Take x>y and let t=x-y>0.

The solution is given. In this tutorial we shall evaluate the simple differential equation of the form $$\\frac{{dy}}{{dx}} = {e^{\\left( {x - y} \\right)}}$$ using the method of separating the variables. The differential equa 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. Thus you are looking at all possible combinations of values of X and Y that add to z. Find dy/dx e^(x/y)=x-y. Differentiate both sides of the equation.

For example when: 2 4 = 16. Then. log 2 (16) = 4. Logarithm as inverse function of exponential function. The logarithmic function, y = log b (x) is the inverse function of the exponential function, x = b y About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators May 16, 2018 · If xy=e(x-y), show that dy/dx=logx/{log(xe)}2.
