expand (cot(θ)+csc(θ))^2

expand

(cot (θ) + csc (θ))^{2}

cot^{2} (θ) + 2 cot (θ) csc (θ) + csc^{2} (θ)

Solution steps

(cot (θ) + csc (θ))^{2}

Apply Perfect Square Formula:

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

(cot (θ) + csc (θ))^{2} = cot^{2} (θ) + 2 cot (θ) csc (θ) + csc^{2} (θ)

= cot^{2} (θ) + 2 cot (θ) csc (θ) + csc^{2} (θ)

8 (- x - \frac{1}{2})

a (cos (Θ) + Θ sin (Θ))

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

(7 + cos (θ))^{2}

\frac{4 x ^{4} ( 1 - x ^{2} )}{( 1 + x ^{2} ) ^{3}}
