OpenLab #3: Advice for the future

(Due Tuesday, 5/21/19, at the start of class).  Imagine that you are invited to speak on the first day of MAT 2680, to give advice to entering students.  Write at least three sentences responding to one or two of the following, describing what you would tell them.

  1. What do you wish that you had been told at the start of this class, to help you succeed?
  2. Choose one topic in the course that is especially challenging. Identify it, and give advice to students trying to master that topic.
  3. What is the most important prior knowledge (not taught in the class) that you need in order to succeed?  Why is it important?

Extra Credit.  Respond to someone else’s comment.  Do you agree? disagree? Have anything to add?

Assignments Week 12 & WeBWorK NEW FEATURE ‘MathQuill’

New Feature in WeBWorK

WeBWorK now has “MathQuill” enabled by default, which allows more natural “pretty print” input for your answers.  You don’t have to do anything special to use it – once you click in an answer box, it will start working.  It will detect the mathematical symbols you type and display the answer correctly onscreen – (for example, when you type a fraction “/”, it automatically becomes a vertical fraction).  There is also a popup menu with common expressions such as radicals.

WHAT IF I WANT TO TURN THIS FEATURE OFF?  You can control this in WeBWorK under User Settings/Use live equation rendering.

Assignments Week 9

WeBWorK: Assignment  9-Nonhomogeneous  due Tuesday, 4/2, at midnight.

OpenLab:  OpenLab #2: Numerical Methods PROJECT is due Thursday, 4/4, by the start of class.
