i have no idea how to start this

aah thanks!!!!! your very helpful

oh i solved according to what i understand. i usually solve the simple ones first, so that i could determine which equations should i use how about letter c?

i just need some corrections with my solution

thanks, no you did not do my homework, you gave me some ideas i need to pick which side should i be for my argumentative essay. I just wanted to know which side has more points so that I can write a long one..

Topic: "Can collective security work?" Collective security is the cooperation of several countries in an alliance to strengthen the security of each. I need your opinions whether it is "yes" or "no"..

Given |a|=3, |b|=5, and |a+b|=7, determine |a-b|. (a and b are vectors) how to start this?

oh ok, thanks again:)

oh yeah, i'm totally out of the track, i need to do it again :/ thanks am i right now?

hmm.. i need to indicate it's domain so correct me if i'm wrong, the angle must be between 0 and 90 degrees(0°<Θ<90°) right?

i'm not sure if i'm right, i know there's another method in solving this but i'm not sure how to do that

thanks a lot! your so kind

I tried solving this again yesterday, I changed my solution.. I found a different LONG way, but I still get the right answer.. I also tried to do your solutions and both are also right,.. My solution was almost similar with imatfaal, i also used derivative to find the maximum area. Thanks to both of you

i just noticed, I made a mistake! it suppose to be 2Θ not Θ..

An isosceles triangle is inscribed in a circle of radius R. Find the value of theta that will mazimize the area of the triangle

thanks guys, i will gather more information then i will do some important points that supports the Yes side.. do you think it will help me if i also search for the No side? i guess i will do that for now, I'm not sure whether it is good to be on the Pro-sweatshop than anti-sweatshop ..

Hmm.. I need to defend on my side.. I read this article : http://www.slate.com/articles/business/the_dismal_science/1997/03/in_praise_of_cheap_labor.2.html I got your point, but what you posted sounds like you don't agree that sweatshops and cheap labors benefit the poor..am i right?

"Can Sweatshops and Cheap Labour Benefit the Pooor?" I'm on the YES side.. I need some ideas how to defend this Also, can youo please post the links where you get your ideas.. THANKS!!

Wow.. thanks! this is very useful

The point A(2,4,5) is reflected in the line with the equation r=(0,0,1)+s(4,2,1), to give the point A'. Determine the coordinates of A'.

ok thanks:)

f(x)=x+1/x Find all critical numbers. Find where the function is increasing and decreasing. Find critical points and identify each as a relative maximum, relative minimum, or neither. Find second order critical numbers and tell where the graph is concave up and where it is concave down. I'm on the last question now, but i don't know how to find the zeros of the second derivative because i got 2/x^3..i need it to find critical numbers and tell where the graph is concave up and where it is concave down.

nice! By the way, we won our debate! thanks a lot for the ideas..

Wow thanks a lot, now I have lots of ideas on how to defend this.
