Limit(x*sin(1/x), x = 0). As x goes to 0, the limit is 0, but I don't understand why. Please explain.?

Cos(3x-1)=0 3x - 1 = arccos(0) 3x - 1 = pi/2 3x = pi/2 + 1 x = pi/6 + 1/3.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
