taylor ln(x),\at 4

Solution

taylor

ln (x), at 4

Solution

\frac{\frac{1}{at 4}}{1 !} (x - at 4) + \frac{- \frac{1}{( at 4 ) ^{2}}}{2 !} (x - at 4)^{2} + \frac{\frac{2}{( at 4 ) ^{3}}}{3 !} (x - at 4)^{3} + \frac{- \frac{6}{( at 4 ) ^{4}}}{4 !} (x - at 4)^{4} + \dots

Solution steps

Apply the Taylor Formula

= ln (at 4) + \frac{\frac{d}{d x} ( ln ( x ) ) ( at 4 )}{1 !} (x - at 4) + \frac{\frac{d ^{2}}{d x ^{2}} ( ln ( x ) ) ( at 4 )}{2 !} (x - at 4)^{2} + \frac{\frac{d ^{3}}{d x ^{3}} ( ln ( x ) ) ( at 4 )}{3 !} (x - at 4)^{3} + \dots

Evaluate Derivatives

= ln (at 4) + \frac{\frac{1}{at 4}}{1 !} (x - at 4) + \frac{- \frac{1}{( at 4 ) ^{2}}}{2 !} (x - at 4)^{2} + \frac{\frac{2}{( at 4 ) ^{3}}}{3 !} (x - at 4)^{3} + \frac{- \frac{6}{( at 4 ) ^{4}}}{4 !} (x - at 4)^{4} + \dots

Refine

= \frac{\frac{1}{at 4}}{1 !} (x - at 4) + \frac{- \frac{1}{( at 4 ) ^{2}}}{2 !} (x - at 4)^{2} + \frac{\frac{2}{( at 4 ) ^{3}}}{3 !} (x - at 4)^{3} + \frac{- \frac{6}{( at 4 ) ^{4}}}{4 !} (x - at 4)^{4} + \dots
