tomorrow my physics class is racing our solar boat in a competition. because of the weather would it be better to connect the solar pannels in series or parrallel thanks

i hope thats right

if your friends dont wont to come its there loss

yeh i am going with a group of four friends we were all in the fob mosh together and lost each other befor they even came on and did not see each other untill the end

I cant wait to i got mosh tickets

My Chemical Romance are coming Late November

thanks so much you are my new hero

cool but how did you no to times all terms by [(cosα)^2 . (sinα)^-2]

thanks for ya help but sorry i dont follow how you got to this line dy/dx = -a(cosα)^-2 . -sinα - b(sinα)^-2 . cosα stat. pt occur when dy.dx = 0 0 = a(sinα)^3 - b(cosα)^3 how did you simplify that and go from -2 to 3 and is tan sin/cos so why does b/a give tan and not cot

this picture might even be better

sorry about the picture the question reads A vertical wall in danger of collapse is to braced by a beam which must pass over a second lower wall b metres high and located a meters from the first wall. Let the lenght of the beam be y meters the angle the beam makes with the horizintal be @ and...

it is a trial question

hi could some one plz help with this question

wont find out till i go back to school

thanks heeps

sorry why did yo times by 1/in3^2

sorry i dont follow after the quotient rule

so no one doing 2u can do the last question

no there was no diagram and yes i am sure it is a 2u question it is in a 2006 trail mathematics paper

thanks so much sorry to be such a pain and i guess the last think you want to be doing on the holidays is someone elles home work but can i ask one more question if sin(A+B)=sinAcosB+cosAsinB and Cos (a+B)=cosAcosB-sinAsinB show that tan(A+B) = tanA+tanB / 1-tanAtanB and hence find a similar...
