expand (cot(θ)+1)^2

expand

(cot (θ) + 1)^{2}

cot^{2} (θ) + 2 cot (θ) + 1

Solution steps

(cot (θ) + 1)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

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

= cot^{2} (θ) + 2 cot (θ) + 1

\frac{1}{s ( s + 2 ) ^{2}}

\frac{3 ( 1 - x )}{2 e ^{\frac{x}{2}} x}

(3 - x + 2) (3 + x + 2)

\frac{1}{s ( s ^{2} - 1 )}

\frac{2 x ^{3} + 1}{x ( x - 2 )}
