## How To Use Calculus To Find The Area Of Curve

### Finding the area under a curve is a central task in calculus. This process is called finding the definite integral. Microsoft Excel does not have native calculus functions, but you can map your

- When approximating the area under a curve using left, right, or midpoint rectangles, the more rectangles you use, the better the approximation. So, “all” you’d have to do to get the exact area under a curve is use an infinite number of rectangles. Now, you can’t really do that, but with the
- Area above and below the x-axis. To work out the area below the -axis uses the same technique as for above the -axis. Example. Calculate the shaded area between the curve and the -axis as shown below.
- Area under a curve using vertical rectangles (summing left to right). We are (effectively) finding the area by horizontally adding the areas of the rectangles, width `dx` and heights `y` (which we find by substituting values of `x` into `f(x)`).
- Finally, unlike the area under a curve that we looked at in the previous chapter the area between two curves will always be positive. If we get a negative number or zero we can be sure that we’ve made a mistake somewhere and will need to go back and find it.
