Welcome to the Trigonometry Course at SchoolhouseTeachers.com!
Welcome to the Trigonometry course. I’m Martha Candler, and I look forward to helping you in the days and weeks to come.
I have chosen to explain in detail the basic topics in a course that is part of the Algebra II sequence, as well as an introduction to additional topics for students in the Pre-Calculus sequence. You will need additional problems to work and an extension of these ideas at times. Just keep in mind that it is not my intent to provide you with a complete course as in a textbook—although it comes close to that on certain topics. Graphing calculator use is explained briefly for certain problems.
A table of contents is included so that you can tell which topics are covered in our 14 weeks of lessons.
Along the way, I have numerous problem sheets, and answer keys, in my lessons.
Thank you for attempting this course and joining me here at SchoolhouseTeachers.com. I hope it has been helpful. I would appreciate it very much if you let me know which parts were the most helpful. Just send a message to firstname.lastname@example.org.

Martha Candler is a mathematics teacher with five years of high school experience and 20 years of teaching math at the college level, most often as an adjunct instructor so that she could be home when her children were home. With most of her experience in College Algebra, Trigonometry, Pre-Calculus, and Business Calculus, her favorite has always been Trigonometry.
She believes that students should understand what they do and not just do the work mechanically or through shortcuts. As much as possible, they should see a reason or use for what they are learning. This is her philosophy when creating extra materials for her classes.
Martha has two married daughters who went through public schools, but that might not be the case if they were school age now, she says. She enjoys reading, needlework, and is very involved in the music program at her church, where she plays piano, keyboard, harp (occasionally), and works with a men’s vocal quintet and a mixed ensemble.
