The distance from a point (x,y,z) to the point (3,1,1) is d= (x−3)2(y−1)2(z1)2 But the algebra is simple if we instead maximize and minimize the square of the distance 2 d =f(x,y,z)=(x3)2(y1)2(z1)2 Constraint 2g(x,y,z)= x y2z2=4 Using Lagrange multipliers, solve ∇f= λ.  y=2(x5)^22 is a continuous function with an infinite number of (x,y) pairs which could be considered solutions There is no "solution" graph{2(x5)^22 14, 6, 908, 092} We could find the solutions for a couple of points that are often of interest The equation itself is in the "vertex form" and we can read the coordinates of the vertex directly from the equation (5,2).

Solve the system by substitution { − x y = 4 4 x − y = 2 { − x y = 4 4 x − y = 2 In Example 515 it was easiest to solve for y in the first equation because it had a coefficient of 1 In Example 516 it will be easier to solve for x. 3 Put the v term equal to zero (this gives a differential equation in u and x which can be solved in the next step) 4 Solve using separation of variables to find u;. Answer (1 of 7) In these summations , we first write the nth term Notice here the nth term will be 1/(n)(n1) It can be written as (n1)n /(n)(n1) =>1/n 1/(n1) Now when you take summations from n=1 to infinity, you can observe cancellation of terms T1 = 1/1 1/2 T2 = 1/2 1/3 T3 =.
