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
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
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
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...
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...
