The original QUESTION: What equation would have the intersection points of the graphs its solutions?
The above didnt make sense to me so the teacher reworded it
PRESENT QUESTION: If you were to find the intersection of both graphs, what equations would you use?
Hint is that these two graphs intersect when both equations are equal.
Im not sure what the question is asking does it want an equation or a solution?
so far I've put both equations equal to each other and after simplifying I've got up to 4sin^2(x)-12sin(x)+9=9(1-sin^2(x)) i don't know what's next or if this is what the question is asking for please help!
