expand (csc(θ)+sec(θ))^2

expand

(csc (θ) + sec (θ))^{2}

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

Solution steps

(csc (θ) + sec (θ))^{2}

Apply Perfect Square Formula:

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

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

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

(n + 1)^{2} (\frac{2}{3})^{n}

9 z^{2} (4 e + 7 f) + 4 e + 7 f

(5 a + b^{5}) l e f t (5 a - b^{5})

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

(x + 4) (x + \frac{5}{6})
