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
