Problem 1: What is the variance of a portfolio with: w1 =0.2, w2
=0.8, σ12 =10, σ22 =20,
and σ12 =5.
Problem 2: a) If the stocks 1 and 2 have negative correlation
12 then their covariance σ12 is
also negative. Yes, no, uncertain. Explain. b) If stocks 1 and 2
are uncorrelated, i.e.
12=0 then their covariance is zero, Yes, no,
uncertain. Explain c) If stocks 1 and 2 have variance
σ2=16 each, could their covariance be equal to...
a) By direct substitution determine which of the following functions satisfy the wave equation. 1. g(x, t) = Acos(kx − t) where A, k, are positive constants. 2. h(x, t) = Ae where A, k, are positive constants. 3. p(x, t) = Asinh(kx − t) where A, k, are positive constants. 4. q(x, t) = Ae where A, a, are positive constants. 5. An arbitrary function: f(x, t) = f(kx−t) where k and are positive constants. (Hint: Be careful with...
