Solve the equation cos(5x) cos(2x) - sin(5x) sin(2x) = 0.74 by first finding exact values for the two fundamental solutions and then using the fundamental solutions to write expressions for all coterminal solutions. Write your answers in degrees. Hint: Use a sum or difference formula to combine the terms on the left hand side. Remember that fundamental solutions are the solutions between 0° and 360°. List the smaller solution first. Fundamental solution #1: Fundamental solution #2: Please use k as a variable when writing expressions for the coterminal angles. Solutions coterminal to fundamental solution #1: Solutions coterminal to fundamental solution #2:
