NLVM's Free Online Graphing Calculator

!9#: NLVM's Free Online Graphing Calculator

It's easy to find interactive graphing calculators websites, but finding a free, easy to use graphing calculator applet that's not buggy is more of a challenge. One of the best is hosted at Utah State University's NLVM site, the National Library of Virtual Manipulatives. If you're not familiar with it, NLVM is an extensive collection of interactive applets for students and teachers. You'll find not shortage of interesting puzzles and games there, but this time we wanted to highlight their "grapher" applet.

What sets apart the NLVM grapher is its simple to use, yet powerful interface. An easy to use menu at the top of the screen allows for fractions, exponents, square roots, and absolute values, and they can all be inputted just as they appear in a textbook. There's very little clutter on the screen to intimidate users.

There are surprisingly powerful options for a Java based calculator. Of course, there is a simple trace feature, which utilizes a slider bar. There are three additional tabs for users to choose from, parameters, window, and functions.

Parameters allows the user to insert up to three parameters into the equation that can be manipulated with a slider bar. If you are interested in examining translations, this is a very powerful feature since the graph adjusts in real time.

Not surprisingly, the window tab give the user the option to adjust the graph view. Fortunately, it is also possible to zoom by simply using the mouse to select a region to view.

The functions tab gives the user the ability to input up to three functions. One of the really nice features here is that composite functions are supported (although inverse functions are not). Other advanced features offer the ability to choose each functions color and restrict domains.

The applet doesn't contain all the functionality of a high end graphing calculator handheld, but that's not really the point. Whether you're a student using it to try out graphing for the first time or a teacher incorporating it into your lesson, it's a simple and reliable solution. NLVM's grapher is one of the best online graphing calculators available today.

!9# Financial Engineering

Financial Engineering is a new exciting branch which deals with creation, management and administration of new financial instruments based on new strategies. Engineering methodologies and mathematics are applied to derive solutions for financial issues. Applied Mathematics combined with financial theories tries to bring out solutions to finance problems.

This is all about creating new securities or processes, and designing new financial instruments, especially derivative securities. This new branch is also considered to be the process of employing mathematical, finance and computer modeling skills to make pricing, hedging, trading and portfolio management decisions. It utilizes various derivative securities and other methods and aims to precisely control the financial risk that an entity takes on. Methods can be employed to take on unlimited risks under certain events, or completely eliminate other risks by utilizing combinations of derivative and other securities.

Financial engineering can be applied to many different types of currencies and pricing options. These include equity, fixed income such as bonds, commodities such as oil or gold, as well as derivatives, swaps, futures, forwards, options, and embedded options. With financial engineering come many risks. Risks are divided into market risk and credit risk. Market risks can be managed using risk identification, risk measurements, and risk management. Credit risks can be managed using credit modeling and credit pricing.

To become a financial engineer, one must have a strong understanding of financial economics, mathematical tools such as probability and statistics and differential equations, as well as have engineering principles such as software engineering.

Financial engineering is normally employed in the securities and banking industries. Mutual Funds and Share broking agencies deploy lot of the state of the art Financial Engineering tools and softwares to handle client accounts and carry out client instructions.

Financial Engineering is a fast growing arm of financial economics and is playing a stellar role in bringing discipline and safety to the high-risk profile Securities trade and business. It is interesting to note that Financial Engineering professionals today earn some of the highest pay checks in the industry thanks to their specialized skills and much-needed expertise.

It is to be born in mind that the arrival of this new exciting branch of engineering has already helped and is set to help many sectors in a big way. Besides bringing in the factors of security and stability to the shaky financial empire, this branch can really enable the tracking and storing of valuable financial data without the risk of being stolen or hacked.

The TI 83 Plus Graphing Calculator can do so much for you when it comes to High School Math, as well as College Math classes. If you're in the market to get one today, I wanted to point out why you should get it, and what it can do for you, when it comes to calculating formulas.

Perfect for the ACT, SAT, and PSAT, this handy calculator can do just about anything you can tell it to. In fact, it can even do the formula just like it is in your math book. For example, if you have a problem in your book, you can download the App4Math app and it can figure out the problem for you. There's no more trying to figure out how to do it all on the calculator.

Key features on the TI 83 Plus Graphing Calculator:

It has an upgradable operating system and software, where you can always stay on top of technology, and you don't have to worry about your calculator becoming obsolete.

You can now download study apps like the ones I talked about above. You can compare these to the apps on the systems such as the iPhone. This is great for adding additional software to your phone.

If that's not enough, you can also make it compatible with older editions such as the TI-84 and TI-84 Plus Silver.

With a one year's warranty, it's no wonder why many students tend to take this route when it comes down to getting a calculator for the classroom.
