MATH 147 Precalculus

This is a single course equivalent to College Algebra (MATH 143) plus Trigonometry (MATH 144). Credit hours are not granted in both MATH 143 and MATH 147 nor in both MATH 144 and MATH 147. NOTE: For convenience of the student schedule, Math 143 and Math 144 may be taken concurrently in lieu of Math 147.
