• Lesson
  1. (5.2) Verifying Trigonometric Identities
     
     • Guidelines
       1. Work with only one side of the equation at a time. Usually it is better to start with the more complicated side first.
       2. Look for opportunities to factor an expression, add fractions, square a two term quantity, or create a single term denominator.
       3. Look for opportunities to use the fundamental identities. Note which functions are in the final expression you want. Sine and cosine pair well, as do secant and tangent, and cosecant and cotangents.
       4. As a last resort, convert all terms to sine and cosine.
       5. Always try something. Even paths that lead to dead ends give you insight.
