# MATH 1435 - Precalculus II: College Trigonometry

Credit Hours: 3.00

Prerequisites: MATH 1415  with grade C or better, or an equivalent college course or an acceptable score on a placement or prerequisite exam

(formerly MATH 1430)

No credit after MATH 1430, MATH 1450, MATH 1460, or MATH 1465. MATH 1435 is the second of two courses whose combined content with MATH 1415 parallels that of MATH 1465. Topics include algebraic and geometric review of the essentials for trigonometry, triangle trigonometry, analytic trigonometry, trigonometric identities, trigonometric functions, inverse trigonometric functions, polar coordinates, polar graphs, and vectors.
