expand-1/((arctan(x)-x)^2)

expand

- \frac{1}{( arctan ( x ) - x ) ^{2}}

- \frac{1}{arctan ^{2} ( x ) - 2 x arctan ( x ) + x ^{2}}

Solution steps

- \frac{1}{( arctan ( x ) - x ) ^{2}}

(arctan (x) - x)^{2} = arctan^{2} (x) - 2 x arctan (x) + x^{2}

= - \frac{1}{x ^{2} - 2 x arctan ( x ) + arctan ^{2} ( x )}

\frac{( x , y )}{( 2 , - 3 )} + k (1, - 6)

x z (x + 3 y + 5 z)^{2}

(5 x + 8 \circ x^{2} + x) (x)

(2, - 1) y (- 1, \frac{9}{- 7})

\frac{7 ( - 4.9 x ^{2} + 250 )}{7 x - 50}
