Use the squared identities to simplify 2sin^2xcos^2x
Rainbow [258]
\bf sin^2({{ \theta}})=\cfrac{1-cos(2{{ \theta}})}{2}\qquad \qquad 

cos^2({{ \theta}})=\cfrac{1+cos(2{{ \theta}})}{2}\\
-----------------------------\\
thus
\\\\
2sin^2(x)cos^2(x)\implies \boxed{2}\cdot \cfrac{1-cos(2{{ x}})}{\boxed{2}}\cdot \cfrac{1+cos(2{{ x}})}{2}
\\\\
\cfrac{1-cos(2{{ x}})}{1}\cdot \cfrac{1+cos(2{{ x}})}{2}\implies 
\cfrac{[1-cos(2x)][1+cos(2x)]}{2}\\
-----------------------------\\
\textit{now recall}\implies \textit{difference of squares}
\\ \quad \\


\bf (a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)\\
-----------------------------\\
thus
\\\\
\cfrac{[1-cos(2x)][1+cos(2x)]}{2}\implies \cfrac{1^2-cos^2(x)}{2}
\\\\
 \cfrac{1-cos^2(x)}{2}\impliedby
