Function Analyzer (freeware) http://lib.giveawayoftheday.com/Function_Analyzer_173317/ is a program that draws the graph of a function with one variable declared by the user. The operators used to build the mathematical expression are the usual ones used in software calculators: * for multiplying, / for dividing, ^ for power and so on. Parentheses can be used to group terms in your expression. Trigonometric functions are also supported, along with a few log operators (bases 2,8,10 and 16). The interface of the program is minimal: one window, two entries of the top menu (help and about) and all the tools needed to create and adjust the graph are placed at the bottom of the window. Two axes split the graph area in four quadrants but that’s not enough if you want to analyze certain points of your function. The lack of a grid and divisions on the axes make it almost impossible to know where to find a certain value on one axis. A workaround for this problem is moving the graph to a corner of the window and getting your values this way (in each corner, the coordinates are displayed). This is an interesting, educative application. It’s hard to understand why there are no divisions on the axes and no grid because, excepting this lack, the program is well-constructed. Review licensed from Publisher description Function Analyzer is a program that permits you to see the graph of a function like f(x)=. The usage is very simple: - Write the function expression in the bottom combo box or choose and modify a predefined one - Press the 'Analyze' button to show the graph. After this you can: - Move the X,Y axis, zoom in/out, increase/decrease precision (more precision you use more time the program take to process the expression).

MathGV (freeware) http://lib.giveawayoftheday.com/MathGV_89012/ Beginning from its name you guess that this application is oriented to people with numbers and calculating skills, so if you are not one of those it’s very likely you won’t be interested in this review. On the other hand, if you are a science person you might be pretty interested. Since its creator is a former user of this kind of applications, MathGV introduces a fresh interface concept with ease-of-use as a primary goal. But, let’s see what MathGV does in further detail. MathGV is an application that will allow you to plot mathematical complex expressions in four different styles of coordinated spaces: two dimensional functions, polar, parametric, and 3 dimensional functions. One of the advantages of using this type of software is the better understanding of mathematical functions that graphical representation allows. Up until now this application is available as a freeware but take into account that the producer intends to make money from future versions so now would be a well moment to get your free edition. Have in mind that MathGV will only generate graphs of mathematical functions and won’t be able to generate graphics from raw data points. Let’s take a look to the following list which enumerates the capabilities of the MathGV: 1. MathGV can plot up to 5 function types: 2D Cartesian (X, Y), parametric, polar, 3D Cartesian (X,Y,Z), 2D function rotated into 3 dimensions. 2. MathGV can create graphs containing more than only one function. 3. All graphs are drawn on resizable bitmaps, and displayed in scrolling windows. 4. Graph bitmaps can be copied and pasted into other programs, or saved to disk. 5. Multiple document interface (MDI) allows for simultaneous viewing of multiple graphs. 6. MathGV can calculate negative numbers to fractional powers. 7. MathGV includes a Function Calculator that can give decimal or fractional results. 8. The changes you make are automatically displayed in the graph windows, so you get to preview in real time. 9. MathGV provides tool bar buttons to zoom, rotate, and page up, down, left, and right. 10. Graphs can be saved in bitmap (bmp), jpg or MathGV format. 11. MathGV provides a label tool bar for drawing, lines, free hand lines, rectangles, circles, round rectangles, flood fills, and text. 12. Labels can be selected, dragged, dropped, resized, added and deleted on any graph at any time.
