So we want to look at what is the identity that takes co sign of you minus cosine of the And this is although it&#x27;s a difference. It&#x27;s listed as one of the some to product forms, and so if we think of it that way, we can see it&#x27;s, ah, some or plus negative. It&#x27;s a difference. You know, you&#x27;re right down forms that this will equal negative two times the sign, interestingly enough, and it&#x27;s a product. They&#x27;re gonna be a product of two functions. Both will be sign, and we take u plus V over to so basically finding the average of the angles times the sign of U minus to be over to. And not that this question asked this. But remember that if you have this being a plus, it&#x27;s not as simple as just saying, Oh, just change this to a plus. It becomes a totally different formula, but it&#x27;s still going to be a product of two functions, but that becomes the product of the cosine of the same angle you plus B over to times the cosine of U minus v over to. So this is the one that with the question is asking about. So we&#x27;re going from a difference to a product

Hello, everybody. Welcome. We want to fill in the blank to complete the trick formula. Cosa New times cause envy is equal to what? So this is just one of those formulas after just gonna have to remember and just memorize them. Uh, and I guarantee they&#x27;re going to be quite useful in the future. So, um, this we know that cause I knew times cause envy is equal to half times co sign of you minus V. And I&#x27;ve color coded the V just because I know you and we can look quite similar sometimes. Plus close sign of you plus video, you plus me. And so this is our This is our property. Um, essentially tells us that because I knew times cause envy is equal to 1/2 off co sign humans replace cause I knew plus B, thank you for watching. And I hope this helps

alright in this problem were asked, Do sign you. I&#x27;m school Sandy and we&#x27;re doing this product some rules and it&#x27;s just really just rewriting the rule. The one half times fine you u Plus B Why sign U minus B. And that&#x27;s the answer. It just really wanted you to do the formula.

do you Sweet. You know that we have a former for this. So because you let speed equal to you time minus saying so.

Ankit Gupta · Answer

we know that. Same You wait three. It could too. You all right? Called sweet Minus. I mean called shoot. So that is all my nose.

Ankit Gupta · Answer

digital does sign you sign, Be equal toe have, oh course u minus B minus because you bless.

Sheryl Ezze · Answer

we can notice that CO sign of you minus coats. I of a Is this one of our some to product formulas in the state so that people can get to sign You cost me over too times sine you minus me over too.
