This is a table...
Concentration of Chemical A, x....|1 | 2| 3 |4 | 5 | 6 |7
Concentration of Chemical B, f(x)|12|16|18|21|24|27|32
Let me know if you need help figuring out that table.
So the 3 questions I am having trouble with are as follows.
a) Plot points and connect them with line segments (I can do this)
b) Use the trapezoidal rule to find the area bounded by the broken line of part a, the x-axis, the line x=1 and line x=7
c)Then approximate the area again using the Simp rule
You have to sum the areas of the 6 trapeziums below
For the second one that I have indicated in blue :
where does the 2 come from in the numerator?
