taylor sqrt(x),x=4

taylor

x, x = 4

2 + \frac{1}{4} (x - 4) - \frac{1}{64} (x - 4)^{2} + \frac{1}{512} (x - 4)^{3} - \frac{5}{16384} (x - 4)^{4} + \dots

Solution steps

Apply the Taylor Formula

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

Evaluate Derivatives

= 2 + \frac{\frac{1}{4}}{1 !} (x - 4) + \frac{- \frac{1}{32}}{2 !} (x - 4)^{2} + \frac{\frac{3}{256}}{3 !} (x - 4)^{3} + \frac{- \frac{15}{2048}}{4 !} (x - 4)^{4} + \dots

Refine

= 2 + \frac{1}{4} (x - 4) - \frac{1}{64} (x - 4)^{2} + \frac{1}{512} (x - 4)^{3} - \frac{5}{16384} (x - 4)^{4} + \dots

\int \frac{3 x + 1}{( x - 2 ) ( x + 3 )} d x

\int x - ln (x) d x

\int_{0}^{\frac{π}{8}} cos^{2} (2 x) d x

x^{5} cos (x^{2})

\frac{d}{d x} ((3 x)^{5 x})
