The CLP calculus textbooks and problem books were written for standard university Calculus 1, 2, 3 and 4 courses at the Department of Mathematics, UBC.
The authors are three UBC Mathematics Department faculty, Joel Feldman, Andrew Rechnitzer and Elyse Yeager who wrote the texts and problems during (roughly) 2015-2018.
The initial impetus for writing the texts was the ever rising cost of textbooks.
The text and problems were originally written in LaTeX, and were translated to PreTeXt in order to create the mobile versions (with help from both Rob Beezer and David Farmer). The images for the text were produced using a mixture of TikZ, Inkscape and tools produced by Joel Feldman.
