Answer:

 lim_{x \to0}( \frac{ \sin(\pi - \pi \cos {}^{2} (x) ) }{ {x}^{2} } )  \\  =  lim_{x \to0} \frac{ \sin(\pi(1 -  \cos {}^{2} (x) ) }{ {x}^{2} }  \\  =  lim_{x \to0} \frac{ \sin(\pi \sin {}^{2} (x) ) }{ {x}^{2} }  \times  \frac{\pi \sin {}^{2} (x)}{\pi \sin {}^{2} (x) }  \\

All right here is very cool trick i used to solve limit if you don't know . whatever in sin function any complex function or anything if it is going for zero and there is same function in denominator so it will be 1 .

So your limit becomes

lim_{x \to0}  \frac{\pi \sin {}^{2} x}{ {x}^{2} }  = \pi
