This one is very similar to Problem 1, although there is a very important difference. So, what are these angles? Now we come to the very important difference between this problem and Problem 1. The solution is NOT. Note the difference in the arguments of the sine function!
This makes all the difference in the world in finding the solution! Therefore, the set of solutions is. However, it makes the point. However, most of the problem is identical. In this case the solutions we get will be.
Notice the difference in the left-hand sides between this solution and the corresponding solution in the previous problem.
They will on occasion and you need to get used to seeing them. Note as well that it is possible to have one of these be a solution and the other to not be a solution. It all depends on the interval being used. We would have completely missed four of the solutions!
So, our solutions are. This is a trick question that is designed to remind you of certain properties about sine and cosine. This problem is a little different from the previous ones. First, we need to do some rearranging and simplification. Again, we need to do a little work to get this equation into a form we can handle. The easiest way to do this one is to recall one of the trig formulas from the Trig Formulas section in particular Problem 3.
If you divide both sides by a cosine you WILL lose solutions! Note that in this case we got a repeat answer. So, all together we get the following solutions,. This problem appears very difficult at first glance, but only the first step is different for the previous problems. So, why cover this? Well, if you think about it there is very little difference between this and the problem you are asked to do.
First, we factor the equation. Often both will yield solutions! This problem, in some ways, is VERY different from the previous problems and yet will work in essentially the same manner.
First, get the sine on one side by itself. Also, make sure that your calculator is set to do radians and not degrees for this problem. It is also very important to understand the answer that your calculator will give.
