Presentations
MATH 1720

Students enrolled in this course are required to view the PowerPoint presentations (online or on CD) before doing the homework.  Viewing the presentations diligently has proven to greatly increase learning of the course material!

These presentations are animated!  To advance a slide and/or its animations, click somewhere on the slide --- or press the spacebar on your keyboard.  Do not use the playback controls at the bottom of the slide, except when you want to return to a previous slide.  (Doing so will skip over the animations.)

Keywords:    Each lesson contains a keyword on a selected slide (chosen at random).  Students are required to submit this keyword; it is one of the questions in the Mod Check (do NOT send the keyword by email).  When you see a keyword, jot down the lesson number and the keyword to submit after you have finished viewing the presentation.

To view a Presentation ONLINE, click on the Lesson number in the first column.  If the Presentation fails to open, CLICK HERE.  To hear the Audio Lecture that goes along with the slide Presentation, click on the corresponding number in the second column.

To view a Presentation ON CD, insert the disk in your CD drive, open an "Explorer" window, and 2-click on the desired Presentation.  To hear the lecture, you must also 2-click on the corresponding mp3 audio file.

After viewing the Presentation, close (or minimize) the extra window; the current browser window will still be open.  Then click on Next Topic in the Action Menu above to move on to the next step in the Module.
