TI89 Titanium or Casio Classpad 330 recommended. Prerequisites: MTH 252 and its prerequisite requirements. Audit available.Addendum to Course Description
This is the third course of four courses in the Calculus sequence.
Intended Outcomes for the course
Upon completion of this course the learner should be able to do the following in the outside world:
• Analyze real world scenarios to recognize when elementary differential equations, vectors, or series are appropriate, formulate problems about the scenarios, creatively model these scenarios (using technology, if appropriate) in order to solve the problems using multiple approaches, judge if the results are reasonable, and then interpret and clearly communicate the results.
• Appreciate elementary differential equation, vector, and series concepts that are encountered in the real world, understand and be able to communicate the underlying mathematics involved to help another person gain insight into the situation.
• Work with elementary differential equations, vectors, and series in various situations and use correct mathematical terminology, notation, and symbolic processes in order to engage in work, study, and conversation on topics involving vectors and series with colleagues in the field of mathematics, science or engineering.
• Enjoy a life enriched by exposure to Calculus.
Outcome Assessment Strategies

Documentation Standards for Mathematics
All work in this course will be evaluated for your ability to meet the following writing objectives as well as for mathematical content.
 Every solution must be written in such a way that the question that was asked is clear simply by reading the submitted solution.
 Any table or graph that appears in the original problem must also appear somewhere in your solution.
 All graphs that appear in your solution must contain axis names and scales. All graphs must be accompanied by a figure number and caption. When the graph is referenced in your written work, the reference must be by figure number. Additionally, graphs for applied problems must have units on each axis and the explicit meaning of each axis must be selfapparent either by the axis names or by the figure caption.
 All tables that appear in your solution must have well defined column headings as well as an assigned table number accompanied by a brief caption (description). When the table is referenced in your written work, the reference must be by table number.
 A brief introduction to the problem is almost always appropriate.
 In applied problems, all variables and constants must be defined.
 If you used the graph or table feature of your calculator in the problem solving process, you must include the graph or table in your written solution.
 If you used some other nontrivial feature of your calculator (e.g., SOLVER), you must state this in your solution.
 All (relevant) information given in the problem must be stated somewhere in your solution.
 A sentence that orients the reader to the purpose of the mathematics should usually precede symbol pushing.
 Your conclusion shall not be encased in a box, but rather stated at the end of your solution in complete sentence form.
 Remember to line up your equal signs.
 If work is wordprocessed all mathematical symbols must be generated with a math equation editor.
