MAT256 Study Guide - Final Guide: Inverse Trigonometric Functions
Document Summary
Instructions: you have twenty minutes to complete the quiz. You are not allowed the use of notes of any kind. Anyone with a cell-phone on their desk or person will receive an immediate fail. Your answers must be complete and show all work to receive full credit. Good luck: (5 pts) show that is not an inner product on r2. hu, vi = u1 + u2 + v1 + v2, (5 pts) u = (1, 3) relative to the standard basis of r2. Find [u]b if b = {(5, 1), (1, 1)} is a nonstandard basis of r2. S. childress: (5 pts) for the vectors (1, 2, 0, 5, 7) and ( 3, 0, 0, 4, 1) in r5 nd the exact angle between them. The word exact means do not give a decimal approximation. Leave your answer in terms of an inverse trigonometric function: (10 pts) let hf, gi1 = z 1.
