taylor 1/(1-z^2),0

taylor

\frac{1}{1 - z ^{2}}, 0

1 + z^{2} + z^{4} + z^{6} + z^{8} + \dots

Solution steps

Apply the Taylor Formula

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

Evaluate Derivatives

= 1 + \frac{0}{1 !} z + \frac{2}{2 !} z^{2} + \frac{0}{3 !} z^{3} + \frac{24}{4 !} z^{4} + \frac{0}{5 !} z^{5} + \frac{720}{6 !} z^{6} + \frac{0}{7 !} z^{7} + \frac{40320}{8 !} z^{8} + \dots

Refine

= 1 + z^{2} + z^{4} + z^{6} + z^{8} + \dots

\frac{\partial}{\partial x} (\frac{1}{2} ln (x))

(x^{2} + 1) y^{^{'}} + 8 x (y - 1) = 0, y (0) = 3

\frac{\partial}{\partial x} (4 x^{2} - 4 x y + x yz)

\int \frac{tan ( x )}{1 + cos ( x )} d x
