Just like your favorite graphics calculator in high school, Kalgebra is a scientific calculator and has 2D drawers and other functions.
If you have been staring at the Ti-80 series calculators in high school, but later you have not moved it, then you may sometimes eager to revisit those exciting algebra and micro-integral years. Someone in the Linux KDE project must also have this feeling, because there is a KDE framework library Analitza provides related syntax and small components that allows you to use K series applications (such as graphic calculators Kalgebra) to perform advanced mathematical functions.
Install Kalgebra on Linux
On Linux, you can install Kalgebra from the software warehouse. For example, on Fedora, Mageia and similar devices:
On Elementary, Linux Mint, and other Debian -based distributions:
Or, you can install it with Flatpak.
Kalgebra is the same as many famous graphics calculators used in schools. It is both a scientific calculator and a 2D drawer. But unlike any graphic calculator I used to use, it is also a 3D drawer. But before entering 3D space, start with some basic grammar.
When representing equations in Kalgebra, you must make some small translations on mathematical symbols, because they are usually handwritten and need to understand their ways on the computer. For example, to convert the degree of Fahrenheit to the degree Celsius, the formula is: (5 ÷ 9) × (n-32), where N is the Hua Shi. This is usually the expression of equations and mathematical functions: they use special symbols such as ÷ and × and variables such as n, and then they determine which variable represents what kind of value. You don’t necessarily know the meaning of each special mathematical symbol, but as long as you know that special symbols have a specific meaning, then you can find it. In temperature conversion examples, symbols are common, so you may already know ÷ except and × indicate multiplication.
In Kalgebra, like most programming languages, the except method is represented by the positive slash, the multiplication is represented by the star number.
Kalgebra also has special functions for common mathematical operations. When you enter any letter in Kalgebra, the tool prompts will provide potential automatic complement functions for available functions. Another way to write temperature conversion equations in Kalgerbra is to use
Times (5/9, 70-32)
When you complete the mathematical problem, the determined variable will be listed in the right column of the calculator, including
Value, this value will be updated according to the answer of the completed equation. Then, theoretically, you should be able to reverse the conversion and obey
Rebirth of Hua’s temperature.
Numbers are interesting, but when they are used to draw shapes, they really become interesting. The visualization of the two -dimensional space on the graphic is an important skill in the development of all disciplines, and the most important of which is computer programming.
To draw a line on the graph, you must set a horizontal value (X -axis) or a vertical value (Y axis), or both settings. In common mathematical symbols, an effective linear equation is
x = 5
Essence This will generate a horizontal line at 5 points above the 0 origin of the graph. However, in Kalgebra, you must make it clear that you just want to use symbols
To set the x value.
In addition, drawing is as simple as elsewhere. You can write complex equations, and you can use special functions, such as
3D picture on Linux
When you enter the 3D graphics tab, you may have well understood Kalgebra’s grammar, and also exceed my mathematical knowledge. I learned all the knowledge about Descartes from electronics and synthesis, so the most interesting thing for the 3D map is to consider the sine waves into 3D objects:
The difference between 3D chart and 2D chart (except one -dimensional) is that there is only one graph in the 3D chart, so please choose the equation wisely.
Is mathematics fun?
It turns out that yes, mathematics can be very interesting, and the answer is a good graphics calculator. When I have been making up for some quite bad mathematical results in the past, I want to use the calculator. I found that Kalgebra is a very useful tool, which can not only solve any problems, but also understand the grammar of the equation and the purpose of the function. Regardless of your mathematical results, please take out your Kalgebra calculator and run some numbers. This is really interesting.
