and period of period of why equals cosign times three The angle. Now here. Remember that in order to do this, we have to have our A and R b R A is usually we find with the Cosa we would find a co sign and be of our angle. Well, in this case, we don't have an A there, but just kind of like a like a coefficient with a variable that would be the same as one and B what equal three. So to find our amplitude, our amplitude is gonna be the absolute value of a. So in this case, that's gonna be the absolute value of one which is one on our period because we're talking about cosign that's going to be weaken. Do either, um, radiance are degrees. We're gonna do this within degrees. That's gonna be 360 degrees divided by the absolute value of B. So that would be 360. Divided by absolute value of three or 3 60 divided by three, which would be 100 in 20 degrees
