7-6 Solving Trigonometric Equations Finding what x equals

Solve for x: It is just like solving regular equations, but once you get solutions, you have to find corresponding angle measure.

Find solutions all solutions on one pass around the unit circle.

What are the rules? 1.“x” means give the answer in radians; “Θ” means give the answer in degrees. 2.“Solve for 0 ≤ x ≤ 2π” means give all the answers on one pass around the unit circle. 3.“General solution” means give one formula to represent every solution. 4.Guess what: Work on both sides of the equation using all the rules of algebra. That is a) Isolate the function or b) factor

Is that it? Well, yes, except for one footnote. Never Never Never Never divide both sides by the same trig function to get rid of it. For example, Why? Gold star to the person who can tell me.
