Question

1 – limit x tends to 0 sin(pi cos 2 x) / x 2 2 – L = limit x tends to 0 a – (a 2 -x 2 ) 1/2 - x 2 4 ___________________ x 4 a>0 , if L is finite , find the values of a and l....???? plz provide detailed solution for the second question.....

Shubham Singh · Answer

for first question apply L’ Hopitol rule second question is not clear

astha · Answer

... lim (x→0) [ sin ( π cos² x ) ] / x²

= lim (x→0) { sin [ π ( 1 - sin² x ) ] } / x²

= lim (x→0) [ sin ( π - π sin² x ) ] / x²

= lim (x→0) [ sin ( π sin² x ) / x²

= lim (x→0) [ ( π sin² x ) / x² ] ....................... from (1)

= π • [ lim (x→0) ( (sin x) / x ) ]²

= π • [ 1 ]²

= π ........................................... Ans.
