Express the given product as sum or difference containing only sines or cosines_cos2(Simpliiy your answer )

Express the given product as sum or difference containing only sines or cosines_ cos 2 (Simpliiy your answer )



Answers

Transform the product into a sum or difference of sines or cosines with positive arguments. $$2 \cos 2 \cos 3$$

Guess what. You're at the falling product for a Sorry. This is the difference as a product. So we get negative to sign of data plus three data over to. And then we'd have sign of data minus three data over two. So what does this give us? We have negative to sign of two data and in sign of negative data. Now, let's recall that sign is an odd function. So that means if we have of negative X, we can rewrite this as negative FX. So let's pull out this negative sign. So we have negative times Negative instead of positive. So this here is our final solution.

Okay, So what's your rate? The following product. As a some sign, I still have a product of sign and coastline. So this is equal to 1/2 of sign of ricchiuto over to plus data over to. And then we have plus sign of 30 over two minus data over to. So it's simple Fortis. So we get 1/2 fine of four data over two. So that's two data. Then we have plus sign of three minus one, which is two. And then you have 2/2. So that's his equal today. Okay, so we get the falling solution.

So this problem will be using a product to some formula to write this product of triggered a metric expressions as a self, if you're gonna matching expressions. So we have sign and co sign scientists co sign. So let's let a equal to X and be equal X. Then we would use the formula to get that this equals to 1/2 I'm sign of a cluster B just three x plus sign of a mind speak, which is X So this is our final expression after we've converted it to a some

So in this problem, we will use a formula that converts products just sums in order to rewrite this product as a sum of side and co sign expressions. So we're going to be using the Formula Co. Sign of a Chance Co. Sign of P is equal to 1/2 Times Co sign of a plus B plus co. Side of a minus. So let's identify A and B We could do it either way as its communicative, But let's let two s over three the hour a. For example, three will be so. Then we can write this. It's equal Teoh 1/2 Times Co sign of a plus B a plus B. It will be six x over three. So that's two X plus co sign of a minus bi, which will be negative two X over three and then this is currently correct. But the book does favor not having negatives in because co sign is even co sign of negative bucks is equivalent to co side effects. So it's a stylistic choice. Either way is totally fine, but we also can be right this as co sign of two X plus co sign of a positive two X over three. So either of these expressions will serve as our final answers to this problem
