Embry MATH112 Module 1 Discussion
Module 1 – Discussion: Application CIN Problems
Upon completion of this assignment, you will have an overview of calculus and discover the tools that are available for you to use in this course.
In each module, you will work two custom problems based on your unique Calculus Identification Number (CIN) provided by your instructor. Your instructor will assign this five digit CIN once you have sent an confirmation email as instructed in the Start Here module (you may already have received it). The letters that are in bold in brackets below correspond to you CIN. The first digit is [a], the second digit is [b], etc.
You are encouraged to view and comment on your classmates’ posts. Sometimes it is helpful if you are having difficulty to ask how they arrive at their solutions. To do this, use the Reply button associated with their orignal post.
Problems
Find the slope of the line passing through the points ([c], [d]) and (1, [b]). The write-up for this problem should be one line in MathType. Round your answer to two decimal places.
If f\left(x\right)=\left[a\right]-\left[b\right]x+x^2\: and g\left(x\right)=\frac{x}{x-\left[c\right]+1.5}g(x)=xx?[c]+1.5 , find
1. a) f\left(g\left(\left[d\right]\right)\right)f(g([d]))
2. b) g\left(f\left(\left[d\right]\right)\right)g(f([d]))
Round your answers to two decimal places.
Grading: This posting will be graded out of 100 points. If you receive an unsatisfactory grade, you may rework and repost the problem. You may receive help from your classmates or look at their postings to see where you went wrong. You may continue working on this posting until the last day of the current module.

Embry MATH112 Module 2 Discussion
Module 2 – Discussion: Newton and Leibnitz
When you read the textbook introduction pages to the four chapters that we cover in this course (Chapters 23-27), you are introduced to a number of famous mathematicians. Sir Isaac Newton and Gottfried Leibnitz are the two mathematicians who are credited with the creation of calculus. They are our persons of interest for this discussion activity.
Your discussion activity for this module is to research these two men and write a couple of sentences about each of them. Your goal is to add a new fact to the Discussion Board about each of these men.
Add to the discussion by using theReply feature. Before you add your post, make sure no one has already added it. Unlike other Discussion activities, you will be able to view everyone’s responses before your initial post. If you post by the due date and add a new fact about each of these men, you will receive full credit for this discussion activity.
This activity rewards those who do not procrastinate. The first ones to post will have an easy time adding a fact. Those who procrastinate will need to read through all of the posts and then search out a new fact. If there is a question in your mind about whether or not your fact is different from those already posted, then find something else. These facts should be no longer than two sentences. This is not a paper; there is no extra credit for posting a ton of information.
