# Project #77607 - Online computer calulating programs

I need someone who is familiar with these math websites. Has a good knowledge of college Algebra. And good writing skills. I need some to graph and describe a math problem using these websites. Desmos Online calculator (www.desmos.com), Wolfram Alpha (www.wolframalpha.com), Geogebra (www.geogebra.org), or a graphing calculator.

• For A1, you will come up with a polynomial equation of degree 3 or higher.  (You will need to use the same equation for your real-world problem in part A2).  You will graph your equation using 2 different technologies.  I recommend the Desmos Online calculator (www.desmos.com), Wolfram Alpha (www.wolframalpha.com), Geogebra (www.geogebra.org), or a graphing calculator.  There are many others….it is your choice.  You must include the picture or a screen shot of the graph from both technologies in your task.  Then, you will ANALYZE the graph.  That just means give some general attributes of the graph – like intercepts, domain/range, minimum/maximum etc.  Finally, you need to compare the two technologies.  What does one do that other does not etc.
• For A2, you will create your real-world problem.  Write it out, describe what the variables represent, what you are trying to solve for etc.  Volume is a common topic used for this section, but you are welcome to use whatever you want!  A search on the internet may help.  Graph your equation using CAS (computer algebra system) technology.  It can be the same as one you used for part A1 as long as it is a CAS.  Wolfram Alpha is my recommendation.  It is a free CAS application. This time your screen shot should show the SOLUTION to your word problem using the technology.  I suggest writing a short description of HOW you found that solution using the technology as well.  Be sure to give your solution using the appropriate units.
• For A3 and A4, you are writing about the advantages and disadvantages of using a CAS (computer algebra system) in the classroom.  Be sure you have 2 of each.  Focus on the calculating capability of a CAS which is what makes them different than ‘normal’ graphing utilities.
