Hint :differentiate both sides of the identity
I can't use differentiation. :-(

Now subtract from both sides: But the right side of the equation now equals , so solve for it in the equation below. Obviously, this method is not as fast as differentiation.
Look this is simple. If then

What's a good method to show that the limit exists for this sequence? I've tried showing that it's contractive, but no luck there. Tried the ratio test, didn't work for me. Any ideas?
