# What Precalculus knowledge is required before learning Discrete Math Computer Science topics? [closed]

Below I've listed the chapters from a Precalculus book as well as the author recommended Computer Science chapters from a Discrete Mathematics book.

Although these chapters are from two specific books on these subjects I believe the topics are generally the same between any Precalc or Discrete Math book.

What Precalculus topics should one know before starting these Discrete Math Computer Science topics?:

i'd go for none - but this isn't the right place to ask – jk. Oct 9 '12 at 19:15
The prerequisites depend on the book or course, there's no useful general rule. Sometimes the author or lecturer assumes no prior knowledge, sometimes they assume basic familiarity, sometimes they assume strong bases. Ask your lecturer or check the preface of the book. – Gilles Oct 10 '12 at 0:52
