Exams
 A sample final exam is available HERE. (Update on problem 7c: M=maxf). The solution can be found HERE.
 The final exam is now available. You can download the exam HERE. For MATH423/CAAM423 student, the exam will take 200 minutes. For MATH513/CAAM523 students, the exam will take 4 hours. You can use the textbook, your own lecture notes and your own homework assignments during the exam. Other communications and helps are not allowed. You should spend no more than 200 consecutive minutes (or 4 consecutive hours) on the exam. Please submit your exam to my office on Wednesday December 13th, between 10am12pm, 2pm4pm.
 The solution of the final exam is available HERE.
 Exams are under the honor code. Be sure and hand in all the work you do on each problem. Good luck!
