X-GraphCalc

X-GraphCalc is a comprehensive yet user-friendly application that comes in the form of a statistical calculator that can generate 2 D and 3D graphs with calculated equations and functions. It also comes with a script library for doing area, surface area, volume or circle attributes.

The program doesn't require an installation and can be directly run from a thumb drive on any computer. It's suitable when you're on a trip, and you need a reliable tool to make complex calculations for your projects. It doesn't leave any traces behind after it's been deleted nor takes too much space on the disk.

It's wrapped in a neat and easy-to-use layout divided into three distinct tabs, namely output, graph, and 3D graph. The calculator is positioned separately from the sections to easily enter the values. You can insert them either by manually pressing the calculator buttons or using the Numpad keyboard.

The simple operations that can be done are the addition, subtract, multiplication, and division. X-GraphCalc lets you do the square root, exponential, natural logarithm, cosine, sine, tangent, cotangent, along with power, and EE. From the Tools menu, it's possible to calculate the area (e.g. circle, ellipse, equilateral triangle), volume for the cube, cylinder, sphere, pyramid, as well as the radius, and quadratic equation.

From the graph tab, you can select the type of analysis you want to do, which can display areas, draw tangent lines, and measure the distances. Each line may be customized with a distinct color,  while the representation can be saved as an image to the drive. From the options, it's possible to choose the mode (Euclidean, Polar coordinates, parametric), set the equation for each line, as well as configure the precision and value range.

Taking everything into account, X-GraphCalc is a reliable program designed to offer a simple yet professional method to calculate complex equations, trigonometric functions, and generate 2D and 3D graphs. During our testing, the tasks were executed swiftly and didn't encounter any issues.
