There are many different graphing calculators that you will find on the web with different functions and features; however, the best graphing calculators online are those that are suitable to your educational level and your requirements. The features of the online graphing calculators that were designed for college level students is definitely not advisable for those in their high school years considering that the subjects being taught are different. Prior to purchasing a graphing calculator, it is important to make an assessment as to how it will be used since complex calculations may warrant the CAS graphing calculator.
CAS graphing calculator
CAS stands for Computer Algebra Systems and graphing calculators that have this feature are usually designed for the manipulation of symbolic expressions and geared towards students and scientists who utilize more complex and sophisticated features. The CAS graphing calculator can also evaluate, factor, integrate, solve roots and simplify an equation at the touch of a button. A non-CAS graphing calculator is typically ideal for high school students who need to cope up with Math and Algebra subjects. Simple and affordable graphing calculators are suggested for high school students but if they progress to advanced Calculus, the CAS graphing calculators will help in solving equations. As the student progresses to higher learning, more advanced features will be required.
Standard features of graphing calculators
The best graphing calculators online have standard features that include:
- Graphic display screen where mathematical expressions are displayed in the same way that they are written manually.
- In order to be adaptable to different devices, most graphing calculators have USB capabilities.
- Best graphing calculators online have 2D and 3D graphing capabilities with a variety of functions over the x-y-z areas.

These companies are widely known for the quality of their products but checking their websites is suggested since there is usually a list of features for each type of graphing calculator. It also makes sense to check with your teachers since schools have different policies on graphing calculators. Some mathematics teachers encourage the use of graphing calculators in class particularly in calculus courses while others disallow the devices in physics and chemistry classes because they contain the features of periodic tables. Graphic calculators with CAS and 3D graphic features might not be acceptable in some schools. It makes sense to check the school policies before purchasing the calculator.
Since a graphing calculator is considered an investment, you will want to determine the reliability of the vendor or if there is a return policy in case you are not fully satisfied with the product.
