Truncation of order 2?

I do not understand how to do the question in part b.

Suppose I show that the function is twice differentiable (how do i do so), is that sufficient to show that the 'method' (does this refer to the prediction-correction method) has a truncation order of 2?

What is truncation?

Please see attached image.
I have the solutions for this question, however I do not understand them one bit. If anyone would like me to post them, I'd be more then happy too.

thanks



EDIT: I've solved this.

In order to show for a truncation of order 2, there are two conditions which must be satisfied. That is all the question is asking.

Thanks anyway.

So what is meant by "truncation?" My journey into the depths of Google didn't really get me anywhere. I know it has to do with the accuracy of the area calculation, but couldn't get further than that.
