WebSorted by: 2. The expectation of a sum is the sum of expectations, so. E ( cos ( x + y)) = E ( cos x cos y) − E ( sin x sin y). For independent variables, the expectation of the product (of any functions f ( X), g ( Y)) is the product of expectations, so you can expand the products, too. Share. Cite. Web1 Answer. Sorted by: 2. The short answer is because the sine wave is the slowest at the peak. If you imagine a pendulum (which is basically a sine wave ), it's slowest at the extremes, and fastest at the bottom. As a sine wave the pendulum's bottom is the zero, and the extremes are -1 and 1. Since, the pendulum is slowest at the extremes it ... scream face svg free
