Course Plan
Date: August 1, 2012 - 2013
MAT 121, Algebra/Trigonometry I
2 lecture hours and 2 lab hours for 3 semester hours credit
Course Description: This course provides an integrated approach to technology and the skills
required to manipulate, display, and interpret mathematical functions and formulas used in
problem solving. Topics include simplification, evaluation, and solving of algebraic and
radical functions; complex numbers; right triangle trigonometry; systems of equations; and
the use of technology. Upon completion, students should be able to demonstrate an
understanding of the use of mathematics and technology to solve problems and analyze and
communicate results.

Grading Policy: Grading policies will be included in the syllabus and distributed to all students
at the beginning of each semester. In all curriculum math courses the grading scale is the same:
A =100-90, B = 89-80, C = 79-70, D = 69-60, F = 59-0.
Disability Services: Alamance Community College is committed to providing equal educational
opportunities for students with documented disabilities. Students who require disability services
or reasonable accommodations must identify themselves as having a disability and provide
current diagnostic documentation to the Disability Services Office located in the Gee Building,
Room 128. All information is confidential. Please contact Monica Isbell, Coordinator of Special
Needs & Counseling Services for more information at 336-506-4130 or email at
isbellm@alamancecc.edu.
Student Access to Faculty: Instructors will provide students with a written syllabus that
includes their name, office number, telephone number, e-mail address and office hours.
Attendance Policy: The standard ACC attendance policy will be followed (see the ACC
Student Handbook for details.) The attendance policy may be modified by departments as
approved by the Associate Dean. The specific attendance policy for this course will be provided
in the syllabus.
Academic Integrity: Students should review the Student Code of Conduct section of the Student
Handbook.
