how 2 expand this equation...........(1-x^2)^4..?
Dear arun
(1-x^2)^4 can easly expand by binomial theorem
if you want to expan with the help of calcus
(1-x2)4 = a0 + a2 x2 + a4 x4 + a6 x 6 +a8x8
put x=0
a0=1
now twice differentiate and put x=0 you will get value of a2.
further twice differentiate and put x=0 you will get value of a4
similerly for others
