The Simple is the Best

HighSchool-Calculus (Larson et al.)

We selected the textbook

"Calculus with Analytic Geometry 6th edition" written by Roland E. Larson Robert P. HostetlerBruce H. Edwards

printed by Houghton Mifflin Company

Page numbers and examples are all refered from the above textbook and therefore readers can compare the original contents with the present descriptions.

Although the textbook includes a large number of problems, only standard problems are selected to describe the application examples of Cemmath.

Also, due to our limited resources, explanation of Cemmath will be added later, and only short scripts for execution are included. For the time being, most commands may be refered from the tutorials of Cemmath.
