a) Prove, using the joint density function, and the definition of expectation of a function of two continuous random variables (i.e., integration) that E (5X + 7Y ) = 5E (X ) + 7E (Y ). b) (h) Prove, using the joint density function and the definition of expectation of a function of two continuous random variables (i.e., integration) that Var (5X + 7Y ) = 25Var (X ) + 49Var (Y ) + 70Cov (X; Y ).

If the function u (x, y) is a harmonic conjugate of v (x, y) prove that the curves u (x, y) = st. and v (x, y) = stations. are orthogonal to each other. These curves are called level curves. Now consider the function f (z) = 1 / z defined throughout the complex plane except the beginning of the axes. Draw them level curves for the real and imaginary part of this function and notice that they are two...

This is considering the Phi function (The Euler Phi Function) (a) Explain why φ(m) is always even when m ≥3. (b) φ(m) is rarely a prime number. Find all numbers m so that φ(m) is prime. I'm solving for part b. From part a, it looks like there is no prime number for phi of m when it's greater than or equal to 3. Now, I notice that Phi of 4 is 2, Phi of 3 is 2, and Phi...

for unit quaternions used to represent rotations for 3D prove that : a) quaternion conjugate corresponds to rotation inverse ( Approach 1: negate the angle in the formula for converting from the axis-angle form and apply trigonometric identities. Approach 2: convincingly discusses what negating and axis description does in terms of rotation effects and in terms of the formula) b) negated quaternions represent the same rotation ( hint: add 2PI to the rotation angle in the axis angle formula, explain...
