AngieW in Texas Posted February 28, 2009 Share Posted February 28, 2009 You work with sines and cosines in the Geometry book. Jacobs doesn't have a Trig book though - just Algebra and Geometry. Quote Link to comment Share on other sites More sharing options...
Ruth in Canada Posted March 1, 2009 Share Posted March 1, 2009 You can use Foerster's Alg & Trig for both algebra II and trig--or many people use it for a year of algebra II and then move to pre-calculus for trig and advanced algebra.
