Hello

hope you are doing great. As per your query  I would glad to tell you that

this question can be solved by the formula log(1+x)/x when x tends to zero convert log argument(sinx) in the form of 1+x by adding and substractin 1 and then multiply numerator and denominator by sinx-1 . then whole log part will become 1 and you will be left with  sinx-1 on putting x=0 the result will be -1
