Algebraic Equation

Regene DePiero 9/5/2011 Overview: This site is geared toward students in math courses.  It provides a number of online calculators to help solve anything from equations to derivatives.  Its layout is a little confusing after in depth exploration.  Some links do not work or content listed is not what is actually provided.  Also calculators do not offer step by step explanation which only helps students get an answer, and not learn anything about the process.  From a teacher's perspective, not an ideal tool for actually learning math. Content: There is no clear author or sponsor listed.  Information appears to be correct but many of the calculators do not return answers for many problems attempted.  There are almost no actual math explanations provided, only tables and answers.   There is no revision date listed, merely a copyright date at the bottom of the page.  There are links to other pages on the site but most are actually ads and not specifically sponsored but the site itself.  Several links are broken, however there is a link to contact for more information.   Design: This site is confusing to navigate.  What appear to be links to other pages on the site are actually ads.  Several links either do not work or bring you back to the page you were on.  The calculators seem like helpful interactive tools until put into use.  They are difficult to use and there is not a good explanation as to how to input the problem so that they are solved properly.  Also several calculators don't even return an appropriate answer.  Links to "courses" and "lessons" actually only bring you to pages with tables of equations.

Review of how to solve systems of equations by the graphing, sustitution, and elimination methods.

How to use sine,cosine,tangent to determine side X in the triangle below Step 1) Based on your givens and unknowns, determine which sohcahtoa ratio to use Since we know the 67 angle, its adjacent side length and we want to know length of the opposite side, we should use tangent Step 2) Set up an equation based on the ratio you chose in the step 1 $ tan(67) = \frac{opposite}{adjacent} $ $ tan(67) = \frac{x}{14} $ (Let's Step 3) Cross multiply and solve the equation for the side length.

Emily Phillips 8/31/2010 Overview: The purpose of this site is for a quick and easy way to solve simple math problems that only involve numbers, not concepts. The intended audiences are math students in lower levels of math. No available resources are provided. This site is basically a calculator with many functions, but can't do all of the functions that a more advanced graphing calculator can. While the site was easy to navigate, moving advertisements and pictures are distracting to the user. Content: A user can easily tell if this site will help their needs however in order to have full access to the site (i.e. the ability to see the steps to get the answer to the entered equation) they must be a member of the site. The information is accurate but since the answers are computer generated, once the user enters into calculus equations, they should be careful to check their answers with other sources because there is a chance that the answer could be one that is not the appropriate answer. There are no links to other sites that might be helpful or related to the subject. Design: The design was good and easy to navigate and follow. The pages within the site come up fairly quickly and the designs of each page are consistent. Some of the graphics contribute to the site but the advertisements definitely take away attention to the site.

Overview: S.O.S Mathematics is a free resource for math help for high school, college and adult math students. The website reviews all different math subjects ranging from Algebra to Differential Equations. You can also get help regarding specific topics rather than the subject as a whole. The website has more than 2,500 math pages that are easy- to- understand and helpful. This website also helps with test preparation and offers 'Cyberboard', which is a help forum used to ask specific math questions. Content: The homepage loads quickly but there is an advertisement pop-up along with an advertisement on the top of the homepage. Above the advertisement is a toolbar with links to each subject of math. There is a wide variety of subjects that are available to the student for help. There is a current copyright date on the website and the content appears up-to-date. At the bottom of the homepage is the company's contact information. When clicking on a subject, lists of sub-topics are included under that subject, which makes navigation on the webpage easier for the student. Design: The content of this webpage may be very helpful to students, but the design of the website is a bit bland and boring. The design does not look very up to date. The design of this website could potentially turn away a student looking for help at first glance because it's not appealing to the student.

Posted by Amber Rittenhouse on 1/24/10 Overview: This site is used primarily for educational reasons. It is intended for high school students and beyond. The site offers help in many areas of math in order to help with the understanding. Links are provided to get more help beyond what is provided in the site. This site accomplishes its purpose of teaching very well through the example problems given and the lessons provided. Content: This site offers help in order to learn many math concepts, including algebra, trigonometry, calculus, differential equations, complex variables, and matrix algebra. Once you select one of these categories, you can then pick a certain area within the subject. It then offers you an example problem and solution. It is very easy to navigate around the web page. The site offers a lot of information and a lot of help to better learn many math concepts. It does list the date that it was last revised, so the viewer can tell how accurate the information is. Links to other sites are provided to get more help. There are very few ads, so you are not distracted from the learning. Design: The site is very well designed. It is not hard at all to get to a certain subject area that you would like further help in. The site is not incredibly colorful, but this does not distract the viewer from their learning. There is a lot of useful information in this site, so it is definitely worth visiting if you need help in math.
