I have this Trig. problem. y=cos(4t) + sqrt(3)*sin(4t)
I'm supposed to express it in terms of y=A cos(u-v) :confused:
Any help would be appreciated! Thanks!

sanitykey,

We appreciate all the work you put into that post, but unfortunately it is against Physics Forums Guidelines (which you agreed to) for you to do so much. Troll has to show some work on this problem before he can receive help. I've "soft deleted" your post and will restore it if Troll shows us that he is trying.
 
Sorry i got carried away, i understand i shouldn't of done so much. To be honest i found that problem quite challenging the method didn't come to me instantly (which i wasn't sure was right but i guess it is ok since you've looked over it Tom). What I'm trying to say is i'll try not to overdo it next time, i appreciate the time you're taking to modify my post Tom and I'm just glad to help :redface:
 
Troll, as Tom Mattson also mentions, before we can answer your questions,
you need to post what you have tried or where you are getting stuck. Then we can help point you in a successful direction.
