This course provides a transition from computational mathematics to abstract, proof-based mathematics. The primary focus of the course is the development of skills to read, understand, and produce proofs of mathematical statements that explore key concepts from number theory, algebra, and analysis. Topics include set theory, functions, relations, order properties of real numbers, least upper bound, greatest lower bound, the completeness axiom, and limits.

- Translate formal mathematical statements that are written in the standard language and symbolism used by mathematicians. (CCC 1, 2, 4, 6; PGC 2)
- Categorize, identify, and examine common techniques used in constructing mathematical proofs. (CCC 1, 2, 4, 6; PGC 2)
- Communicate a formal mathematical proof. (CCC 1, 2, 4, 6; PGC 2, 4)
- Evaluate the validity of a proposed formal mathematical proof. (CCC 1, 2, 4, 6; PGC 2)

See Core Curriculum Competencies and Program Graduate Competencies at the end of the syllabus. CCPOs are linked to every competency they develop.

Upon completion of this course, the student will:

- Translate formal mathematical statements that are written in the standard language and symbolism used by mathematicians.
- Analyze the essential components of a mathematical statement.
- Use formal mathematical definitions to deconstruct mathematical statements.
- Apply logical connectives and quantifiers to evaluate mathematical statements.

- Categorize, identify, and examine common techniques used in constructing mathematical proofs.
- Analyze mathematical statements to construct a logical structure for a proof.
- Apply direct proof methods to show the validity of mathematical arguments.
- Use indirect proof methods, including contraposition and contrapositive, to show the validity of mathematical arguments.
- Apply the principles of induction to logical argument.
- Analyze a logical argument using cases.

- Communicate a formal mathematical proof.
- Integrate accepted mathematical techniques to construct a formal mathematical proof.
- Write a mathematical proof with sufficient explanation and logic.
- Produce a written proof using acceptable word processing software that captures correct mathematical symbolism.

- Evaluate the validity of a proposed formal mathematical proof.
- Read and synthesize a formal proof into language that is easily understood.
- Scrutinize a mathematical proof in order to verify its validity.
- Expand the deductive argument in a formal proof to better communicate the line of reasoning.

Students must demonstrate proficiency on all CCPOs at a minimal 75 percent level to successfully complete the course. The grade will be determined using the Delaware Tech grading system:

92 | – | 100 | = | A |
---|---|---|---|---|

83 | – | 91 | = | B |

75 | – | 82 | = | C |

0 | – | 74 | = | F |
