www.mathcentre.ac.ukTrigonometric equations mc-TY-trigeqn-2009-1 In this unit we consider the solution of trigonometric equations. The strategy we adopt is to find one solution using knowledge of commonly occuring angles, and then use the symmetries in the graphs of the trigonometric functions to deduce additional solutions. Familiarity with the graphs
