I just finished writing some exercises for the trigonometric identities chapter of a high-school mathematics textbook. The sections I wrote exercises for were called Investigating Compound Angles, Double Angle Formulas, Proving Trigonometric Identities, Solving Linear Trigonometric Equations, and Solving Quadratic Trigonometric Equations. I hope to have more work to do very soon. Also, don’t forget that tomorrow night at 7:30 PM is the nationwide screening of the movie Spirit of the Marathon. If you haven’t purchased your tickets yet, I would call ahead before you go, because I heard that many theatres are sold out!
