expand 1/((arctan(x)+c)^2)

expand

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

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

Solution steps

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

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

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

l im x \Rightarrow 2 (x^{2} + x - 6 x - 2)

- \frac{sin ( x )}{ln ( 2 ( cos ( x ) + ln ( π ) ) )}

e ∣ x ∣ (x^{2} + 4 x y - 2 x)
