expand (2-sin(θ))^2

expand

(2 - sin (θ))^{2}

4 - 4 sin (θ) + sin^{2} (θ)

Solution steps

(2 - sin (θ))^{2}

Apply Perfect Square Formula:

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

(2 - sin (θ))^{2} = 2^{2} - 2 \cdot 2 sin (θ) + sin^{2} (θ)

= 2^{2} - 2 \cdot 2 sin (θ) + sin^{2} (θ)

Simplify

2^{2} - 2 \cdot 2 sin (θ) + sin^{2} (θ) : 4 - 4 sin (θ) + sin^{2} (θ)

= 4 - 4 sin (θ) + sin^{2} (θ)

2 cos^{2} (2 t) + 3 (e^{t} + 1)^{2}

(\frac{x}{y} + \frac{y}{x})^{2}

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

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

\frac{x + 6}{x}
