please show all steps and label them and also calculate the b values (1 point) The second order equation 3xy- 4xy + (x2 + 2)y = 0 has a regular singular point at x = 0, and therefore has a series solution y(x) = Σ Cnxhtr NEO The recurrence relation for the coefficients can be written in the form of Cn =( [2(n+r)(n+r-1)+5(n+r)] DC-2, n = 2, 3, .... (The answer is a function of n and r.) The general...
Please help!! 5 stars please step by steps and ill leave an amazing comment asap (s) Under the standard OLS asumptions, the estimator jbtained from a regression of y, on X, without a constant is consistent ifAo=0 O True O False (h) Suppose that X, N(0,1) and that X,, i-1,..,n are i.id. Then Vn( -0) is well-approximated by a normal distribution
