Write each expression as the product of two functions. $$\cos \frac{\theta}{2}-\cos \theta$$

In this problem for 53 we need to express. We need to express cost three s minus Cost five X cost three x minus. Cost five x as the product of totally automatic functions. So we will be using formula Sign A are not sign a sorry, of course. A my anus. Cosby, which is equal to minus to sign a les bee over to sign a minus bi over to. Okay, so if you compare these two, we will be having a call to three x and vehicle tow fireworks. So course three x minus. Course five x will become minus tool science three X plus five x by two Saying three x minus five x by to it is minus two. Sign eight x by two Saying minus two x by toe. This will be for this will be gone. So Mina stool sign. Forex sign minus six No signed minus X always becomes minus sine x. So finally, this miners and this miles make it plus, So do science. Forex. Sane X. So this is the answer. Thank you. So

We have our number 55 in which we need to express. We need to express costs. Five X minds caused to works because five x minus cost two x as a product off to geran a magic functions, so we will be using formula course A minus. Costs be equals two minus Still saying a plus B right toe science a minus Bi bi do so. If you compare these two, we have a call to five x and be equal to two weeks So because five x minus Cost two x will be equal toe minus to sign fire. X plus two x over two Sign five x minus two works over to so this will be called toe minus to sign seven x by two saying three x by to so this is that answer. Thank you so much.

Number 68. And this we need right Course 5 to- Corset as product of two tech automatic functions. So if this is X, this is why. So this is just like Cossacks minus cause Y, which is equal to minus two Sine X plus Y by two. So five liter blessed peter 62 x two and fine X minus Y by 25 theater minus theater. So 4 3, 2 x two. So there's 2 3. This is too So minus to sign three theatre Sine two theta. So they should be the answer.

We have our number 64 in this village, right? Expression caused three heater Plus cause five ft as on the product of two functions. So this is just like cause explains cause why? Which is equal to to cause X plus Y to cause X-plus y by two because X minus Y by two. So this is to cause 5 30 plus three, 3 to 82 by two. So for theater and of course minus theater now cause minus theater is always cost theater. So too. Mhm. Cause for theater and cost theater. So they should be the answer. Thank you.
