1. The problem statement, all variables and given/known data Use the taylor's expansion of f(x)= x1/4 about x= 16 to estimate (16.1)1/4 2. Relevant equations Taylors formula: f(a) + f'(a) (x-a) + (f''(a)/2!) (x-a)2+...... 3. The attempt at a solution Ok I have calculate the taylor expansion to be: 2 + (1/32) (x-16)-(3/320) (x-16)2+ (7/262144) (x-16)3 I just don't know what to do after this - do i just substitute 16.1 into the value for x in the taylor expansion I have just found?
