Web20 sep. 2014 · Suppose that X and Y are independent n (0,1) random variables. a) Find P(X2 + Y2 < 1) Attempt: a) Let U = X2 + Y2, V = Y. Then X = √V2 − U, Y = V. J = − 1 … WebHere we will look at solving a special class of Differential Equations called First Order Linear Differential Equations. First Order. They are "First Order" when there is only dy dx, not d 2 y dx 2 or d 3 y dx 3 etc. Linear. A first order differential equation is linear when it can be made to look like this:. dy dx + P(x)y = Q(x).
