Area between curves
Task 1
Calculate the left Riemann sum and check that it agrees with the "Approximate Area".
Task 2
How does the height of the rectangles depend on the two functions f(x) and g(x)? Write a formula, then check your answer.
Task 3
Write a formula for calculating the area between any two curves f(x) and g(x) from x = a to x = b. Check your answer.
