THE AREA OF TRIANGLE AND SOLVING TRIGONOMETRIC EQUATIONS

                               

In the first part of this unit we will explore the use of trigonometry to find the area of a triangle. In the second part of the unit we return to using algebraic techniques in order to find angular solutions to trigonometric equations which are represented in algebraic form. Key to these solutions will be identifying the “domain” of each equation prior to seeking any solution that may restrict possible answers according to how trigonometric functions are defined.
