4.1 Basic Trigonometric Equations

OpenStax Precalculus 2e — Chapter 7, Section 7.5

Learning Objectives

  • Solve \(\sin(x) = a\), \(\cos(x) = a\), \(\tan(x) = a\) on \([0, 2\pi)\)

  • Find the general solution using periodicity (\(+ 2n\pi\) or \(+ n\pi\))

  • Use inverse trig functions to find principal solutions

  • Distinguish between solutions on a restricted interval vs. general solutions
