Conditioning on the discrete level Example A fair coin is tossed 10 times;More generally, Eg(X)h(Y) = Eg(X)Eh(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 proveV = e x , v = e x (Note that the antiderivative of v is no more complicated than v was — another indication that we've chosen correctly) On the other hand, if we used u = ex, then u = ex would not be any simpler Performing the integration by parts we get x n e x dx = x n e x x n −1 e x dx − uv uv u v If G n(x) = x n e x dx then we

Proof of f(x) g(x) = f(x) g(x) from the definition We can use the definition of the derivativeThis is the simplified form of the fraction We already know that x cannot be equal to 2 or 0, as it makes f(x) or g(x) undefined Now we need to find what number x that causes f(g(x)) to be undefined To do this, we set the denominator equal to 0 22x=0 => 2x=2 => (2/2)x =(2/2) => x=1Solve your math problems using our free math solver with stepbystep solutions Our math solver supports basic math, prealgebra, algebra, trigonometry, calculus and more
