PLz help me in this?

By using squeezing theorem we can prove that

limxsin (1/x) = 0

x -->0

Why couldn’t we have the same result by writing

limxsin (1/x)= limx.limsin (1/x)=0.limsin (1/x)=0 ?

x -->0 x-->0 x -->0

Thanks for ur help

    First off, can you prove that the limit of a product is the product of the limits?

    Secondly, the limit as x approaches 0 of sin(1/x) is not 0. As x approaches 0, 1/x increases without bound. As it does so, the sine continues to oscillate between -1 and 1, and never approaches a limit. So, even if you can do the proof I mentioned, you're left with the question of what you get when you multiply zero by something which does not exist.
