Trig Sections Didn’t Adequately Prepare Me for Calc
on January 28, 2018
I received an A in the class and while the book was great preparation for the Algebra involved in Calc, it wasn’t particularly great with Trigonometry and very rarely foreshadowed the upcoming topics of Calculus.
I don’t recall the book covering the Double-Angle Formulas, which was a critical component of evaluating Integrals involving Trigonometric Functions, especially semi-circle and Trig Substitution. I also wish the book emphasized the importance of Trig, beyond just the title, and actually how useful memorizing will become. Furthermore, it would have been nice had they mentioned various memorization strategies for Identities and the Trig Ratios. I certainly recommend you Google the Trig Identitiy Hexagon and the Trig Ratio Hand trick. I would have had more appreciation for the topics in this book if they had done some foreshadowing of the upcoming topics in Calculus.
