It's MUCH EASIER TO USE THAN WONDERSHARE PDFelement 6! Which costs $$$$ more than PDFfiller. I could not use the Wondershare PDFelement 6 and got a refund. However if PdfFiller increases it's costs I will attempt to buy the Adobe program. It's not that I use pdf that often that I have to pay a monthly cost.

Create, edit or convert your pdf files. Occasionally I have had to extract some images of pdf files, for which this program has helped me and pleasantly surprised, since the process is very fast and the conversion of the file to images is quite fast and of good quality. Also in some moments I had to create some PDFs myself from photographs or text files, I have also in this process pdffil has been very useful, showing a very good performance and rapids 1.- easy to use. It does not require special knowledge. 2.- process of converting from and to pdf is quite fast. 3.- The results are quite good. 3.- create pdf from word, jpeg, excel or ppt files. 4.- export your pdf files to word, excel or jpg. 5.- You can rotate, cut, join, or create watermarks in your pdf. 6.- You can use it for free (although it has a limit of use per day) 7.- The work environment is simple, but effective. 1.- Sometimes, but due to page saturation problems it becomes a bit slow. 2.- You require constant internet connection so if you do not have access you can not use the online program.

How do you create a Riemann sum?

What do I represent in Riemann sum?

A Riemann Sum is a method for approximating the total area underneath a curve on a graph, otherwise known as an integral. We saw that as we increased the number of intervals (and decreased the width of the rectangles) the sum of the areas of the rectangles approached the area under the curve.

What is the most accurate Riemann sum?

The midpoint Riemann sums is an attempt to balance these two extremes, so generally it is more accurate. The Mean Value Theorem for Integrals guarantees (for appropriate functions f) that a point c exists in [a, b] such that the area under the curve is equal to the area f(c)(BA).

How do you know if a Riemann sum is overestimate or underestimate?

If the graph is increasing on the interval, then the left-sum is an underestimate of the actual value and the right-sum is an overestimate. If the curve is decreasing then the right-sums are underestimates and the left-sums are overestimates.

Why do we use Riemann sums?

In mathematics, a Riemann sum is a certain kind of approximation of an integral by a finite sum. This approach can be used to find a numerical approximation for a definite integral even if the fundamental theorem of calculus does not make it easy to find a closed-form solution.

Why is the midpoint method more accurate?

The advantage of the midpoint method is that one obtains the same elasticity between two price points whether there is a price increase or decrease. This is because the formula uses the same base for both cases.
