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, Codester93

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...

Homework Statement 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 /...

Yeh I get that, could someone please check the rest, it's due tomarrow. >.< And yes they are all the same resistance

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...
