*Demme has changed the way the Online Instruction with Video part of their program works.  It was previously lifetime access to one course; it will now be a one-year subscription for two courses at a time (with the ability to swap courses on demand) and up to five students within those two courses.  Those who already have lifetime access to a single course will retain it, but going forward any new sales will be for the one-year subscription.  See the new Essential Plan Annual Access Card.

PreCalculus

Trigonometry, Identities, Polar Equations, Logarithms, Sequences, Limits, and Other Topics to Prepare for Calculus

PreCalculus combines classic trigonometry with the advanced algebra needed for calculus and other courses. Topics include trig ratios, trigonometric identities, laws of trigonometry, radian measure, polar equations, functions and their graphs, sequences and series, and limits.

The PreCalculus Instruction Pack contains the instruction manual with lesson-by-lesson instructions and detailed solutions, and the DVD with lesson-by-lesson video instruction.

See Student Kit for course content and description.
