Which of the following methods can be used to determine the values of the trigonometric functions of a given angle?
  1. Use your scientific calculator (or your own if you can find it).
  2. Interpolate values from trigonometric tables in your recalculus book.
  3. Derive the values using infinite series equations for sine and cosine functions.
  4. All of the above
Explanation
Answer: D -The following ways can be used to determine the values of the trigonometric functions of a given angle: use a scientific calculator; interpolate values in published trigonometric tables; and derive values using infinite series equations. However, the most time efficient way to determine trigonometric function values is to use a scientific calculator or downloaded app on your smart phone. Published trigonometric tables are heavy to carry, and deriving the answers on your own requires a long and involved effort that may result in frustration and/or consultations with nerdy math professors.
