Anuj s. Best Answer
solution yes question is correct
thank you for the solution but on differentiating sin (1/x) we will get cos (1/x) and than how will we calculate f'(0) if we have just cos (1/x ) without any x multiplied with it
sorry, but cos(1/x) is also discontinuous
sorry for my mistake
cos (infinity) lies between -1 to 1
if you want solution for cos , plz ask , i will give
solution, sorry for inconvenience
