Use the form of the definition of the integral given in the Properties of Integrals to evaluate integrals below:

1.

I then get:

I do the calculations and end up with

Take up the limit as n -> infinite and get

2.

basically I did the same thing for this problem and end up with

Here's another problem that I quite don't understand.

3.Find the Riemann sum for ,

with six terms, taking he saple points to be right endpoints. Give your answer correct to six decimal places.

There are several other parts to this particular question but I think I can manage to answer those if I find out how to do this part.
