MATH& 142 Precalculus II • 5 Cr.

Department

Division

Description:

Prepares students for the MATH& 151/152/153 calculus sequence. Students work intensively with functional trigonometry, polar coordinates, translation and rotation of axes, plane analytic geometry, lines and planes in space, and non-linear systems. Fulfills the quantitative or symbolic reasoning course requirement at BC. Prerequisite: Placement by assessment, or MATH& 141 with a C- or better.
