Reviewed by: CNET Staff
This free calculator's advanced features give it a leg up on many similar applications. The interface doesn't simulate a real calculator, but since GraphCalc has a relatively large number of features and settings, we can understand why the developer needed the extra space. Unlike many common calculators, this program lets you draw detailed graphs in 2D and 3D, as well as analyze functions. The last feature includes such tools as finding an intersection of two functions and drawing the tangent line. If you need to work with statistical or probability equations, you can add the corresponding buttons to the main window. To enlarge the functionality, you can create scripts using if and while operators. You'll also find presets for determining such equations as volume and surface area of various shapes. We think GraphCalc makes a fine free find for anyone who routinely works with complex mathematics.Publisher's description
From GraphCalc :GraphCalc allows you to create, display, and modify 2D and 3D equations. You can modify and display up to six equations, change the range and resolution of the plotted graphs, and manipulate the axes and tick marks to allow easy analysis of the drawn graphs. This program has four render modes and two shading models, providing the flexibility necessary to make the most of your graphs through utilization of OpenGL. Tool tips are attached to every button, giving you a brief description of what the button does.

Version: GraphCalc 4.0.1
Pros: There are many programs such as omnigraph that are very similar to this, but as far as i've seen, this is the only free one. It's deffinately a very usefull for most A level maths courses

Version: GraphCalc 4.0.1
Pros: i think the product has merit and the functions graphed is a convenience if that is something you might need like in school. It performed adequately and the equations are just as you would write them in your homework.
Cons: the screen change is the only thing i did not like.

"Great Program, Minor Problems"
Pros: 3D Graphs -> huge improvement over using a calculator because it looks better and you can manipulate it to look from every angle and resize it.
2D Graphs -> quickly find points on 2D graphs much faster than using a calculator.
Cons: I ran into one minor problem in over a year of using it. If you ask it to calculate the area between two curves and part of this area is below the X axis, it subtracts that part from the area of the top rather than adding it.

"A must have graphic calculator"
Summary: It has functions such trace, calculating min and max, tangent line, area. The interface is beautiful, especially the 3D graphing calculator. You can rotate yourself but you can also let the program rotate for you. One click and you have standard-zoo... read more >>
