10. What would you use to find the approximate area of an integral between certain limits?

Which one of those two does, or does not, give you an area?

You can work this one out yourself.  

Youy only have to know what one of them is because if it is not correct then you will choose the other :)

You can use the "Trapezoid sum" or, "Simpson's sum" or the actual "Integral"....etc.
