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. The correct answer is e^(2x). Just another way to think of it is when you multiply x * x you have x^1 * x^1 and your answer is x^(1+1) = x^2. So e^x *e^x = e^(x+x) = e^2x Find dy/dx e^(x/y)=x-y.

We can try to factor x 2 −2xy−y 2 but we must do some rearranging first: Change signs: y 2 +2xy−x 2 = − 1 k 2. Replace − 1 k 2 by c: y 2 +2xy−x 2 = c. 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! + x 5 5!

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 … Thanks for contributing an answer to Mathematics Stack Exchange!

The second graph is just the opposite. For negative x's, the graph decays in smaller and smaller amounts. E(XY) = E(X)E(Y). More generally, E[g(X)h(Y)] = E[g(X)]E[h(Y)] holds for any function g and h. That is, the independence of two random variables implies that both the covariance and correlation are zero. But, the converse is not true. Interestingly, it turns out that this result helps us prove Random Variability For any random variable X , the variance of X is the expected value of the squared difference between X and its expected value: Var[X] = E[(X-E[X])2] = E[X2] - (E[X])2.
