But what about if the curve forms like a hill ( from top left to bottom right)? Wouldn't that be overestimate?
The diagram you showed was like a slide but what about if it was more like a hill?

[asifalamjoy]

as fas as I can remember the values of x are called abscissa and the value of y as ordinate

There is a method on the scientific calculator where you can click "mode/setup" then table and enter the function, then you can proceed to enter the x coordinates and the h/width value (step) as instructed. Would this be more efficient than manually entering the values in the function?

In this example I am seeing five strips, and not four. I am also seeing five ordinates.
Could someone explain why I am not seeing four strips?

[kidder]

does this mean when we learn integration by substitution, the trapezium rule is no longer needed?

[saeedmiah]

If i were using substitution then what would U equal?

[callumclausen]

How do you know whether or not to differentiate the x+5/x+3?

[ibbypls]

this example is overestimate can you please one underestimate
