EXERCISE 1.73. Prove that every proper rigid motion, f, of R3 that fixes the origin is a rotation about some axis. HINT: Write LA, where A E O(3) with det(A) 1. Notice that A has a real eigenvalue A R, because its characteristic polmomial is cubic Let vi denote a corresponding unit-length is orthogonal, A eigenvector, and complete it to an orthonormal basis (vi, V2,Va) of R. Shou that the matriz representing f with respect to this basis has the...

Thanks so much!
14. Find the vector form and the point normal form of the equations for the plane through the three points P = (3,3,3), Q = (1, 2, 2),and R = (1,5,1). Note that these points are not vectors. Show the calculation of the normal vector. Don't forget to give both forms and show your calculations. [8 points)

Exercise 1. This exercise builds on the method used to prove that if a function differetiable at a point b, then it is also continuous at b. Suppose g : (-1,1) → R is a function such that g(0) = 7 and lim 9)-7-10 exists. Define G())7-10 on-l < x < 1 when x need to know the value of λ, but its existence is necessary in what follows. 0. Let λ be the limit of G(x)...
