1) Find the expressions for the unit vectors in cylindrical coordinate system, p, φ,2. in terms of x, ý, 2. Find the time-derivative of each. Hints: Unit vector p is defined in (x, y) plane. Remember that α -φ is perpendicular to a The easiest way to find φ is to express ρ through φ and add 90 degrees
(4) Write the quaternion group in the usual fashion as Qs = {1,-1, i, -i, j, - j, k, -k) and consider the subgroup H = {1,-1). Write down the multiplication table for Qs/H.
[8] 6. Write the process SARIM A(0, 1, 1) (0,0,1)12 in an expanded form. Call the derived process Xt. Explain why Y7 VXt is stationary. Without calculating the autocorrelation function, for which values of k the value of = Py(k) + 0.
1· (1 point each) Given the array defined below, evaluate each of the expressions and write their value in the space provided. If the expression will cause an error, write "ERROR" in the space instead. Note that each expression is independent. They do not build on each other, so each should be applied to the original array as shown here: int [ ] numbers = {7, 15, 13, 10): a. numbers[O] b. numbers[2] c. numbers[1 + 2] d. numbers[4] e....
