Resources: Final Exam problem 14


This problem requires you to prove a trig identity. I strongly recommend you use the method that we developed to make this easier!


• Handout  Proving trig identities made easier: trig_deliv

• Slideshow with the proof of \cos(x) + \sin(x)\tan(x) = \sec(x): ProvingTrigIdentitiesMadeEasier

[which is the problem proved in the handout and also is essentiqally the problem in today’s Quiz!]
