Question:

Taylor's series is used to expand the function f(x) about a=0 to obtain f(b). f(x) = 1/(3x^3 +4x+8) What are the first two terms of Taylor's series?

Answer:

f(0) = 1/((3)(0)^3 + (4)(0) + 8) =1/8 f'(x) = (9x^2+4)/(3x^3 +4x+8)^2 f'(0) = (9(0)^2+4)/(3(0)^3 +4(0)+8)^2 = -4/64 = -1/16 f(b) = f(a) + (f'(a)/1!)(b-a) = 1/8 + ((-1/16)(b-0))/1 = 1/8 - b/16
