Trigonometry Workbook for Dummies

bought the books for my daughter who is an elgebra teacher, who wants to go on. She is enjoying the books very much and is on the sixth chapter of the trig. book and workbook. She is also working the pre-calculus book and workbook. So far as a mom I'm batting a hundred. Thank you.

I purchased this workbook for my grandson to augment the material he is using in school. It has helped him immeasureably in understanding trigonometry and going a bit farther than the classroom curriculum goes. He has shown increased interest in the subject as a result.

If you have never done trigonometry before, Sterling gives a gentle introduction. She assumes some previous acquaintance with geometry and simple algebra and analytic geometry. But not too much of the latter, so don't let this scare you off. The trig concepts are slowly introduced and explained at some length. With plenty of examples. Now, you really should tackle as many of the problems as possible. Yes, it takes time. But if you want a solid, fluid grasp of trig, you have to spend the time to familiarise yourself with sine, cosine, tangent, cotangent, secant and cosecant. There are certainly numerous relationships between these functions. You don't have to know all of them. But being acquainted with them, and knowing where to look for formulae in a book like this is useful.
