Nice service, but entering in text into some of the fields can result in wonky formatting if more text than can be displayed is entered. And it's not easy to re-visit the fields and edit/shorten the text.

There doesnt seem to be alot of "man in the street" logic to how you explain things. It seems to be written by Code cutters or IT people. Lots of simple things like , I look up how to save a document. You say : Save your document by clicking the 'Save as PDF' button in either the "MyForms" . There is NO such button only a "save as" button. Also Where is the "My Forms" page? is it named as such or .... ????Bascally though, its a great piece of software. You just have to get a REAL human being to rewrite instructions.

I was filling out a stubby pencil application, and thought there has to be a better way. Now I'm happily dragging and dropping scanned files into PDF filler and like magic I have an automated workable document, it's fantastic.

Excellent PDF conversions This software helps me keep documents in unchangeable forms so that they can be sent out and not altered. I love that I do not have to download anything to my computer. I can go straight to the website, upload my document or file, and then have it converted into a PDF within seconds. It is super fast and the PDFs look great. I have used PDFfiller numerous times, and there is not one thing I can think of that I do not like about it.

Declare a variable u and substitute it into the integral: Differentiate u = 4x + 1 and isolate the x term. This gives you the differential, Du = 4dx. Substitute Du/4 for DX in the integral: Evaluate the integral: Substitute back 4x + 1 for u:
Why do we integrate/differentiate equations in Math (or)Physics ? Differentiation reveals the rate-of-change (or instantaneous rate-of-use) of the original quantity or equation. Integration reveals the cumulative effect of the original quantity or equation.
Application in Physics, Integration is very much needed. For example, to calculate the Center of Mass, Center of Gravity and Mass Moment of Inertia of a sports utility vehicle. To calculate the velocity and trajectory of an object, predict the position of planets, and understand electromagnetism.
The Product Rule enables you to integrate the product of two functions. For example, through a series of mathematical somersaults, you can turn the following equation into a formula that's useful for integrating.
Antiderivative and the Indefinite Integral (F(x)+C)=F(x)+C=f(x)+0=f(x). In this definition, the is called the integral symbol, f(x) is called the integral, x is called the variable of integration, DX is called the differential of the variable x, and C is called the constant of integration.
From geometric applications such as surface area and volume, to physical applications such as mass and work, to growth and decay models, definite integrals are a powerful tool to help us understand and model the world around us.
In Electrical Engineering, Calculus (Integration) is used to determine the exact length of power cable needed to connect two substations, which are miles away from each other. Space flight engineers frequently use calculus when planning for long missions.
