A.S.T. Mathematics Degree (for Transfer)

The Associate in Science Degree in Mathematics for Transfer is a degree intended for students transfering to the CSU system with a major in mathematics. To learn more about this degree, please consult the Las Positas College 2017-2018 Catalog, pages 157-158.


New and Upcoming Course Offerings

Math Emporium (Starting Fall 2017)

The Math Emporium is a mode in which students have the ability to personalize the material they learn in their basic skills math courses. This mode allows students to self-accelerate through the material in a way that is unique to each student’s needs. Students will learn study stills and tips along with the math while working on their lab assignments. Students will decide when they are ready to take a test and take the length of time they need when testing (within the hours of operation). Students registering for a Math Emporium Course are required to purchase an use the internet based software MyMathLab, which contains an online version of the Textbook.

Math 39 Trigonometry (Current as of Fall 2016)

Plane trigonometry includes definitions of the trigonometric functions, graphs of the trigonometric functions, trigonometric equations and inverse trigonometric functions, identities, polar coordinates and complex numbers.  Applications involving right triangles, law of sines and law of cosines.  Prerequisite:  Mathematics 55 or 55B or 55Y (completed with a grade of “C” or higher) or an appropriate skill level demonstrated through the Mathematics assessment process.  May not receive credit if Mathematics 36 or 36Y have been completed.  4 lecture hours, 1 laboratory hour. Transfer: CSU; GE: LPC AA/AS.

Math 50 Core Intermediate Algebra (Current as of Fall 2016)

Core concepts of intermediate algebra are explored within the context of the function. Function concepts covered include: distinction between functions and relations, domain and range, function notation, multiple representation of functions, behavior of functions, operations with functions (including composition), and one-to-one and invertible functions. Types of functions considered: linear, absolute value, polynomial, rational, radical, exponential and logarithmic functions. The course includes an introduction to probability, counting and quantitative data. Standards for mathematical practice, applications of functions, and modeling with functions are emphasized throughout. Prerequisite: Mathematics 65, 65B, or equivalent (completed with a grade of "C" or higher) or an appropriate skill level demonstrated through the mathematics assessment process. 4 hours lecture, 1 hour laboratory. GE: LPC AA/AS

Math 51 Algebra Bridge (Starting Fall 2017)

This course is intended for students who completed Math 50 Core Intermediate Algebra and need the equivalent of Math 55 Intermediate Algebra. The course covers content included in Math 55 but not Math 50. Topics include: operations with rational expressions; rational equations; operations with radical expressions; complex numbers; quadratic inequalities and equations quadratic in form; systems of three linear equations; properties of logarithms and logarithmic equations; conicsections; and non-linear systems. Students may not receive credit for both Math 55 and the combination of Math 50 and Math 51. Prerequisite: Mathematics 50 (completed with a grade of "C" or higher) or an appropriate skill level demonstrated through the mathematics assessment process. 2 hours lecture, 0 hour laboratory.

Course Repetition Policy (for replacing a sub-standard grade)

There is a state mandated Repetition Policy for the Chabot-Las Positas District that is retroactive to the date a student first started taking courses within the district (at either Chabot or Las Positas)

What does this mean for students? 

  • Within the district, a student is allowed to attempt a course (or courses equivalent to it) at total of THREE TIMES.  If the first attempt is unsuccessful (W, D, F, or NC (No Credit)), a student has two additional attempts to complete the course with a passing grade (C, B, A or Cr (Credit)).

  • After three attempts to pass a course (or equivalent course), students will be blocked from registering for that course (or its equivalents) again at either Las Positas or Chabot College unless a special circumstance petition is approved, as described in the Administrative Rules and Procedures.
