Let’s Start Some Trig!

Happy New Year!

Usually at the beginning of the year, the PreCalc classes will start you on Trigonometry, which a lot of students loathe….It’s usually not too bad, but you may find that you have to memorize a little more for your trig sections. That’s OK!  Don’t be afraid to do some memorization in your math classes.

Did you know that the word “Trigonometry” means “Triangle Measure”?  That’s what trig is all about – measuring triangles (specifically, angles and sides of triangles).

I find that if the kids I tutor really liked Geometry, they usually prefer Trig to Algebra, since a lot of trig is visual.  But that doesn’t mean there isn’t a lot of algebra in trig…

Here are the sections I’ve completed on SheLovesMath.com on Trig; hope they help (and let me know if I’m missing anything).  Enjoy!   And check out my new Calculus sections – almost done!

Happy Math’ing,  Lisa 🙂
