partialfraction (x^2)/(x^2+1)

解答

多个部分分式

\frac{x ^{2}}{x ^{2} + 1}

1 - \frac{1}{x ^{2} + 1}

求解步骤

\frac{x ^{2}}{x ^{2} + 1}

长除

\frac{x ^{2}}{x ^{2} + 1} : 1 - \frac{1}{x ^{2} + 1}

= 1 - \frac{1}{x ^{2} + 1}

1 - \frac{1}{x ^{2} + 1}

f^{^{'}} x = (2 x) (x^{4} - 8 x) + (x^{2}) (4 x^{3} - 8)

d er i v a t i v e y = \frac{6 t - 3}{5 t + 8}

x \to \frac{π}{2} lim (sin (\frac{x}{2}))

n = 3 \sum \infty (\frac{e}{π})^{n}

d er i v a t i v e \frac{1}{x ^{2} + 1}
