Approximate area by an endpoint or trapezium rule
The data for the approximation are given below
\[p(u)=3\,u + 2\]
The function is increasing on the interval [1, 3]
Use the right-endpoint rectangle rule with 2 equal subintervals of width 1
Give the exact value of the approximation
| Subinterval | Endpoint used | Height |
|---|---|---|
| \([1,\;2]\) | right | ? |
| \([2,\;3]\) | right | ? |
Use the stated rule and give the area approximation to the requested precision
