Problem Statement: Let f(x) = V1 + x. Back in our first semester of calculus, we used a linear approximation L(a) centered at c = 0 to find an approximation to V1.2. In our second semester, we improve upon this idea by using the Taylor polynomials centered at c= 0 (or Maclaurin polynomials) for f(x) to obtain more accurate approximations for V1.2. (a) Compute Ti(x) for f(x) = V1 + x centered at c= 0. Then compute L(x) for f(x)...
