Homework Statement
Cell phone tower #1 has a broadcast radius of 50 miles. Tower #2 has a broadcast radius of 60 miles and is located at a bearing of N 64 W of tower #1. The towers are 100 miles apart
the questions:
A.How much area has coverage by both towers? (dont need the N 64 W)
B.A...
Thanks for answering my questions!:eek: I finally get it!
Sorry if I bothered you but I wasn't at class for a few days and I got behind.
thanks,

I got
cos(3x)=(1/cos(3x)) + 2sec2(3x)-2
then I multiplied everything by cos(3x)/1 and got
cos2(3x)=1 + 2sec(3x) - 2cos(3x)
I looked over my paper and 3 obviously isn't right, but I can't figure out what happens with the 2sec2(3x)-1
1. I got all the answers except I can't figure out how you got 7pi/3. Could you explain how you got that one, because I got all the others.
2. I solved the quadratic and got (y+3) and (y-1) which are sin(3x)=-3 and sin(3x)=1. I can only get 2 answers out of that. Could you explain how to get...
Very nice response! And quick. Well actually a lot quicker than I thought :eek:. Reading though it, it seems that you have cleared up nearly all my questions, but right now its too late for me to be looking into it too deeply. Tomorrow I may be able to look at it in greater detail, but it might...

12cot2(2x)=4
(8 exact answers)
3cos2(3x)=2sin(3x)
(6 decimal answers)
cos(3x)=sec(3x)+2tan2(3x)
(6 exact answers) hint(get all cosines) <- teacher wrote that
And then I have to prove by working on one side:
sin3(x) / 1-cosx = sinx*cosx+sinx
and
(sinx / cosx-1) + (sinx /...
Wats up fellow forumers. I just signed up for physics forum, looks like an awsome forum that I will be as active as I can in. In class I got these circuit questions for review and I just don't know if I know how to figure them out. They are series/parallel brightness questions. It says to order...
