Homework Equations
The Attempt at a Solution
right now i have
f'(x)=1/2x^-1/2
f''(x)=-1/4x^-3/2
f'''(x)=3/8x^-5/2
f''''(x)=-15/16x^-7/2
f'(1)=1/2
f''(1)=-1/4
f'''(1)=3/8
f''''(1)=-15/16
how do i find the coefficient for the nth term?? i keep getting stuck
i tried n/2+1/(-2)^n.. doesn't work
or 1/(-2)^n*(n/2-1)...fail
