taylor x/(2+x^2)

taylor

\frac{x}{2 + x ^{2}}

\frac{1}{2} x - \frac{1}{4} x^{3} + \frac{1}{8} x^{5} - \frac{1}{16} x^{7} + \frac{1}{32} x^{9} + \dots

Solution steps

Apply the Taylor Formula

= 0 + \frac{\frac{d}{d x} ( \frac{x}{2 + x ^{2}} ) ( 0 )}{1 !} x + \frac{\frac{d ^{2}}{d x ^{2}} ( \frac{x}{2 + x ^{2}} ) ( 0 )}{2 !} x^{2} + \frac{\frac{d ^{3}}{d x ^{3}} ( \frac{x}{2 + x ^{2}} ) ( 0 )}{3 !} x^{3} + \dots

Evaluate Derivatives

= 0 + \frac{\frac{1}{2}}{1 !} x + \frac{0}{2 !} x^{2} + \frac{- \frac{3}{2}}{3 !} x^{3} + \frac{0}{4 !} x^{4} + \frac{15}{5 !} x^{5} + \frac{0}{6 !} x^{6} + \frac{- 315}{7 !} x^{7} + \frac{0}{8 !} x^{8} + \frac{11340}{9 !} x^{9} + \dots

Refine

= \frac{1}{2} x - \frac{1}{4} x^{3} + \frac{1}{8} x^{5} - \frac{1}{16} x^{7} + \frac{1}{32} x^{9} + \dots

\int 2 (3 x - 4) d x

\frac{\partial}{\partial x} (e^{x^{2} y} \cdot 2 y x)

\frac{d}{d x} (x^{x} + 2^{x} ln (x))

\int \frac{x - 4}{x} d x

x, x^{2} - 2, - 1, 4
