Since the solutions of the differential equation are y = 2 x 3 C, y = 2 x 3 C, to find a function y y that also satisfies the initial condition, we need to find C C such that y (1) = 2 (1) 3 C = 5 y (1) = 2 (1) 3 C = 5 From this equation, we see that C = 3, C = 3, and we conclude that y = 2 x 3 3 y = 2 x 3 3 is the solution of.

(c) In Rn the set H= fx2 Rn a 1x1 anxn = cg is a convex set For any particular choice of constants ai it is a hyperplane in Rn Its de ning equation is a generalization of the usual equation of a plane in R3, namely the equation axbyczd= 0.

A function may be thought of as a rule which takes each member x of a set and assigns, or maps it to the same value y known at its image x → Function → y A letter such as f, g or h is often used to stand for a functionThe Function which squares a number and adds on a 3, can be written as f(x) = x 2 5The same notion may also be used to show how a function affects particular values. It is important to get the Domain right, or we will get bad results!. The title asks what's the value of n if x and y are given, and in the first paragraph, you're asking what is x n = y if x and n are given univeruser said Please try to keep your method of solving this equation simple, given my inability to understand complicated stuff like logs, antilogs, etc.

You can put this solution on YOUR website!. 0 be a xed point in (a;b), and put y 0 = f(x 0) For su ciently small x, we write y= f(x 0 x) f(x 0) The inverse function gives x= g(y 0 y) g(y 0) Since fis strictly increasing, x6= 0 if and only if y6= 0 By Theorem 417, we know that x!0 if and only if y!0 Hence, by the de nition of derivative, we have g0(f(x 0)) = lim y!0 x y = lim y!0. ( my nx )/( (xy)y )y' = ( my nx )/(x(xy)) y' = y/x Advanced Calculus There is another (often faster) approach using partial derivatives Suppose we cannot find y explicitly as a function of x, only implicitly through the equation F(x, y) = 0 which defines y as a function of x, y = y(x) Therefore we can write F(x, y) = 0 as F(x, y(x)) = 0.

The lesson on inverse functions explains how to use function composition to verify that two functions are inverses of each other However, there is another connection between composition and inversion Given f (x) = 2x – 1 and g(x) = (1 / 2)x 4, find f –1 (x), g –1 (x), (f o g) –1 (x),.

Since the solutions of the differential equation are y = 2 x 3 C, y = 2 x 3 C, to find a function y y that also satisfies the initial condition, we need to find C C such that y (1) = 2 (1) 3 C = 5 y (1) = 2 (1) 3 C = 5 From this equation, we see that C = 3, C = 3, and we conclude that y = 2 x 3 3 y = 2 x 3 3 is the solution of. Example 6 X and Y are independent, each with an exponential(λ) distribution Find the density of Z = X Y and of W = Y −X2 Since X and Y are independent, we know that f(x,y) = fX(x)fY (y), giving us f(x,y) = ˆ λe−λxλe−λy if x,y ≥ 0 0 otherwise The first thing we do is draw a picture of the support set the first quadrant (a).
