How to solve duoble angle formulas with an angle not on the unit circle

1 answer:

6 0

I dont really know how to answer tht but hope this helps....A trigonometric equation is one in which the unknown to be solved for is an angle (call it θ) and that angle is in the argument of a trigonometric function such as sin, cos or tan. A trigonometric equation always has an infinite number of solutions, but it is customary to list only those angles between 0° and 360°.
