  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

Although hyperbolic functions may seem somewhat exotic, they work with the other differentiation rules just like any other functions. For example, with the product and chain rules we can calculate: d dx (5 xsinh 32) = 5sinh 2+5x(3sinh2 2)(cosh x2)(2x).
