Best ResponseYou've already chosen the best response.0the problem doesn't say...just says to use trigonometric identities to find the values

Best ResponseYou've already chosen the best response.0But what is "ᴨ" is it theta or something else. What is it?

Best ResponseYou've already chosen the best response.0expand sin4x, put x as 5pi/8 and equate the expa nsion of sin4x to 1

Best ResponseYou've already chosen the best response.0Do you understand the step "Sin ((27045)/2)=sin (5(pi)/8)"

Best ResponseYou've already chosen the best response.0not really, but i think you got the 270 from 3pi/2 and the 45 from pi/4....

Best ResponseYou've already chosen the best response.0Well, I am trying to express the thing in degree format. (Sorry for using jumbled form). By the term I mean 180 degree

Best ResponseYou've already chosen the best response.0By the term pi mean 180 degree

Best ResponseYou've already chosen the best response.0\[Sin ((3\pi/2\pi/4)/2)=sin (5\pi/8)\]

Best ResponseYou've already chosen the best response.0Now does that makes sense?

Best ResponseYou've already chosen the best response.0Now can you do the rest, or I will have to show you every steps.

Best ResponseYou've already chosen the best response.0so, sin (225/2)=sin (112.5)? you might have to show me the steps.

anonymous

Best ResponseYou've already chosen the best response.0or is it sin (5pi/4 divided by 2)

anonymous

Best ResponseYou've already chosen the best response.0Yes, thats true, but thats not helpful here. \[Sin ((3\pi/2\pi/4)/2)=sin (5\pi/8)\] \[=>sin (5\pi/8)=\sqrt(0.5(1cos(3\pi/2\pi/4))\]

Best ResponseYou've already chosen the best response.0Now you got to use addition formula for cos to solve the part with cos, and then it will be done

Best ResponseYou've already chosen the best response.0I am totally lost .....this does not look at all familiar.....

anonymous

Best ResponseYou've already chosen the best response.0are you familiar with double angle formula for trig?

anonymous

Best ResponseYou've already chosen the best response.0i'm sure we went over them....but nothing coming to mind

Best ResponseYou've already chosen the best response.0Then you can't expect to get this thing within your understandability range

Best ResponseYou've already chosen the best response.0that's why I am having trouble....thought if someone walked me through it, it would make sense

Best ResponseYou've already chosen the best response.0But I don't think they will be very helpful
