WebThe expectation of a linear transformation of X is the linear transformation of the expectation of X. This is a handy result as we will often be transforming variables linearly. Quick Check Let X be a random variable with E ( X) = 5. Find E ( 20 + 2 X − ( 10 − X)). Answer 25 But expectation behaves differently under non-linear transformation. 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.

WebSep 12, 2024 · This equation is satisfied if the argument of the cosine is an integral multiple of π / 2, 3π / 2, 5π / 2, and so on. In this case, we have kL 2 = π 2, or k = π L. Applying the normalization condition gives A = √2 / L, so the wavefunction of the ball is Ψ(x, 0) = √2 L cos(πx / L), − L / 2 < x < L / 2. WebJan 27, 2024 · 1.

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 ...
