#### Course Description

Covers algebra and geometry of special interest to engineering technicians including solving higher order equations, determinants, matrix operations, logarithms and trigonometric identities. Introduces plane analytical geometry in preparation for calculus, emphasizing development of skills and confidence to solve advanced pre-calculus problems. Prerequisites: CMET 112 or MTH 111. Audit available.#### Intended Outcomes for the course

Upon completion of this course, students will be able to:

• Solve applied problems involving trigonometric functions.

• Solve applied algebra problems involving polynomial, exponential, radical, and logarithmic functions.

• Solve applied problems involving analytic geometry and the conic sections.

• Graph conic sections and exponential, logarithmic, and trigonometric functions; both by hand and by using calculator operations and/or computer software.

• Solve systems of equations, graphically and analytically.

• Communicate analysis and results clearly: orally, in writing, and through diagrams and calculations.

#### Course Activities and Design

Lectures and text reading will be the primary presentation methods. The course material is presented in an informal style using the intuitive approach. Formal proofs or theorems are given when they help clarify the presentation. The use of a programmable calculator, as designated by the department, is required for this course to solve certain algorithms.

#### Outcome Assessment Strategies

Based on homework and examination covering appropriate types of quantitative problems. Grading details will be expounded upon by the instructor at the first meeting.

#### Course Content (Themes, Concepts, Issues and Skills)

Upon successful completion of this course, the student will have satisfactorily accomplished the goals and objectives listed in this course content guide. The course content guides are developed by collegewide subject area curriculum committee faculty and approved by management.
