Basic Derivative RulesPre & Post2Option copy and paste error? 6x^2+7 should not appear as an option - or at least I do not see how it related. Remove 6x^2+7 as an option; AW Note: Changing this to 7x^6 for power rule errorYes (Pre)Pending

Basic Derivative RulesPre & Post4Our video uses theta for angle measure.Replace x with theta.Yes (Pre)Pending
11
Basic Derivative RulesPostAllSeems odd to me that this is one of the few videos sets where the PreVideo and PostVideo questions are exactly identical. I can see our instructors wanting them to be slightly different. I did find that they were different on Ximera AFTER I made quick changes to the PostVideo questions on Blackboard. What is on Ximera actually seems good but more challenging than the PreVideo questions.Change the PostVideo questions. You can see provided options to multiple choice questions that did not make it into Blackboard in the "Multiple Choice Question Answer" Google document in our LMS folder. You can also see the actual changes that I made before I realized the Pre and Post should have been different questions. N/APending

26
Definite IntegralsPre and Postquestion involving graph of R(t)The answer choice of "none of the above" is silly given that the question is which value is greatest.Remove "none of the above"YesPendingPending
27
Definite IntegralsPre and Postquestion involving graph of R(t)difficult notation in the Riemann sum choicesReplace symbolic answers with verbal like "Left Riemann sum with 3 partitions for the interval $$ 2 \le t \le 8$$YesPendingThe point of the task is that they equate difficult notation with graphical meanings. No change.

Introduction to OptimizationPost6Some books use "absolute" instead of globalChange to "global minimum (also called absolute minimum) of f(x)"YesPendingPending
76
Introduction to OptimizationPost6Since D was the previous answer in the exact same problem in the PreVideo Questions, students could make D because they marked D before. Change to "global maximum (also called absolute maximum) of f(x)"
And then change answer to B.
The point is labeled D - not going to call it B when it's DNo change
