can sumbody solve this fast!!1


can sumbody help me with the second part first i have done!!!how to do second one
i got partial fractions like
A = 1

C = 8
B=4

and then partial fractions will be
1/(2x+1) + 4/(x-2) + 8/(x-2)^2


now the question is how to do the second part binomially expand????tried it bt a mistake somewhere!!!help

ok, here is the answer..

the perimeter = 2r + rθ
20 = 2r + rθ
20 = r ( 2 + θ )
20/r = 2 + θ
20/r - 2 = θ

i hope you this helped u understand it.

Yes i understood, thanks a lot Khaled!

Divide by (cos Q)^2 everwhere....

then slve the quadratic eqns...where z prob ???

 

[Evana]

lol i know that we have to divide by (cos Q)^2 everywhere but i am a little confused, not sure about the answer :/
