Precalculus Split

What is Math 25 and Math 58?

The Santa Rosa Junior College Mathematics Department  offers Math 27 in a split format, Math 25 and Math 58!

Math 25: Precalculus Algebra (4 units)





Math 27: Precalc Alg. and Trig (6 units)

Math 58: Precalculus Trigonometry (3 units)



Here are some frequently asked questions and answers:


Is taking Math 25 and Math 58 equivalent to taking Math 27?


Yes.  In this case, 25 + 58=27!


Why is Math 25/58 a total of 7 units, while Math 27 is 6 units?


There is some necessary overlap in material for the two classes. Students who take the sequence instead, though it takes longer, material is given in more manageable chunks. It is closer to taking Precalculus in a year, like in High School.


Can I take the courses in order, Math 25 then Math 58?


Yes, as a matter of fact, since success is better achieved that way, we require it now.


Can I take the courses concurrently?


No, Math 25 is a prerequisite to Math 58.


Why should I take Math 25 and Math 58 instead of Math 27?


There are many reasons a student might want to take Math 25 and Math 58 instead of Math 27. Here are a few:


  1. The split version of the course allows a student to cover the material more slowly, over two semesters instead of just one. The two classes allow the student more time to absorb the information presented.  In the Math 58 class, for example, trigonometry will be presented from the beginning of the semester to the end, while in Math 27, the same material is presented over the course of 6 to 8 weeks. 
  2. The split version allows more flexibility in scheduling. 
  3. Students may not have time for a 6 unit class in his/her schedule, but could fit in a 3 unit class.
  4. Students may only need to take the Math 25 (UC transferable and CSU transferable). 
  5. If the student has not passes Math 3 or Intermediate Algebra in high school or they have not taken a math class in five or more years, they will need to take Math 25 with the corequisite support course Math 225 instead of starting with Math 27 right away.

What is the prerequisite for these classes?

Math 25 and 27 all have the same prerequisite:  Completion of Math 156 or Math 154 with a C or better or completion of Math 3 or Algebra II with a C or better in High School. If you have not met this prerequisite, you will need to take Math 25 with Math 225 concurrently, this will provide you with the best chance of successfully completing all of your math classes required by your major.
