expand (cot(x)+1)^2

expand

(cot (x) + 1)^{2}

cot^{2} (x) + 2 cot (x) + 1

Solution steps

(cot (x) + 1)^{2}

Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

(cot (x) + 1)^{2} = cot^{2} (x) + 2 cot (x) \cdot 1 + 1^{2}

= cot^{2} (x) + 2 cot (x) \cdot 1 + 1^{2}

Simplify

cot^{2} (x) + 2 cot (x) \cdot 1 + 1^{2} : cot^{2} (x) + 2 cot (x) + 1

= cot^{2} (x) + 2 cot (x) + 1

- \frac{4 ( - 3 s ^{2} + 12 s - 8 )}{( s ^{2} - 4 s + 8 ) ^{3}}

(x^{4} - 2 x^{2} + 2) l e f t (x^{2} - 2 x + 3)

δ (x - 2)

(2 t - 3) e^{\frac{( t + 2 )}{3}}

\frac{2 n !}{( 2 ( n + 1 ) ) !}
