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.

First, note that I said answer i. Now, we know from our work above that if there is a solution in the first quadrant to this equation then there will also be a solution in the second quadrant and that it will be at an angle of 0.

I did however note that they will be the same value, except for the negative sign. The angle in the second quadrant will then be,. The final step is to then divide both sides by the 2 in order to get all possible solutions. This problem is again very similar to previous problems and yet has some differences. First get the cosine on one side by itself. Note however, that they will be the same except have opposite signs. Now, we need to get the second angle that lies in the third quadrant.

Our calculator will give us the angle that is in the fourth quadrant and this angle is,. If we wanted the positive angle we could always get it as,.
