Dear student
You cqn use L'Hospital rule to find out limit as this is a 0/0 form.
lim x tends to a cos x / 1
now put limit
cos a

we can't use l'Hospital rule in this question
we need to solve this question without using L'Hospital rule
Then use expansion of sin x and sin a...then you will get (x-a) as common which will be cancelled by (x-a) in denominator. and then you will get answer
