Find the coefficients of the first 4 terms of Talyor series of the function f(x)=ln(5+x) centered at 1, and write the corresponding Taylor polynomial, i. e. T(x)=b0+b1⋅(x−1)+b2⋅(x−1)2+b3⋅(x−1) 3. Evaluate differences between exact value of the function and Taylor polynomial approximation a) T(5.5) - f(5.5) = b) T(7.6) - f(7.6) = c) T(10.9) - f(10.9) =
