Step 1

From the given statement, the function f (x) = ln(x), a = 6. help_outlineImage TranscriptioncloseTaylor series of the function fat a is (a)(x-a) n! S()x-a)a (x-a f(a)+ + 1! 2! Start with f(x) Inx, then f(6)-In6. Differentiate f(x) with respect to x, 1 f(x)thenf(6) 6 x Again differentiate f(x) with respect to x 1 then f"(6) 1 (x)- 36 Again differentiate f"(x) with respect to x 2 ,then f"(6) 2 (x)=t =- 216 fullscreen
