Introduction and imagination of mathematics software on iPad

I haven't updated it for a long time, because I am addicted to IPAD recently. I bought an iPad for 4800 yuan, and I have been Tao software on the app store. I would like to share with you a few mathematical software for the iPad. If you are hesitant to buy an iPad, please refer to it. I recently bought a hero and sold the original n82. Therefore, the photo taking effect is not very good.

 
Quick graph is a rare free software that can be used to draw a variety of 2D images. It is especially convenient to study ghost images on the iPad, because you can use the touch screen to freely zoom in, zoom out, and move the viewing range.

 
Quick graph can also draw 3D images and naturally control the angle of view with fingers.

The new version can be used to draw hidden function and inequality images, but the cost is 1.99 USD.

 
 
Although wolframalpha can be used normally with the Safari browser that comes with the iPad, it is much easier to use the official iPad version of wolframalpha. What makes people think is that this software is actually charged and requires 1.99 yuan.

 
The virtual keyboard in wolframalpha has several more frequently-used mathematical symbols and is very practical.

 
 
The symbol computing software on the iPhone/iPad is a software that calculates 1/2 + 1/3 to get 5/6 instead of 0.8333333. Since I have not found the symbolic computing software on s60 and Android, the status of iPad has improved a lot. It's a little expensive. It costs 9.99 yuan. The picture shows the equation x ^ 2 + 2 x = 5. The result is [-√6-1, √6-1].

 
 
Allofwiki offline allows you to download all Wikipedia to the offline browsing software on the iPad, which also requires 9.99 yuan. The software is only 3 MB, and data is downloaded on the iPad. The whole Wikipedia has 5 GB of data. I opened 90 packages in the north of China on the international network and can download more than 100 KB per second. It should be very fast. The entire download process takes more than a dozen hours. You can pause the download in the middle and resume the download in the future.
It is really nice to put the entire Wikipedia into the iPad. Unfortunately, many mathematical formulas, symbols, and images cannot be displayed, and the amount of information they can bring is somewhat limited.

 
 

Finally, we are concerned about using iPad to view PDF-format e-books. I use goodreader, which is quite good at reading e-books. The software is very cheap and only requires 0.99 knives. However, it is best to read books on iBook, especially when turning pages. Unfortunately, there are not many books on iBook, and I have not found many books here.


it is worth mentioning that it is amazing to watch photos on iPad, it can be said that the screen and multi-touch environment of the iPad have completely changed the way photos are viewed on electronic devices. However, unfortunately, in addition to browsing photos and a few other applications, most software still retains buttons, input boxes, dialog boxes and other elements, and seldom jumps out of the operating mode framework of the mouse era. In fact, we can develop a mathematical research environment that many matters dream of on the iPad, not just in imperative Input and Output environments. For example, on the iPad, we can easily implement a scale-out simulator (I don't know if there is such an application ). Click here to add a dynamic point. When the intersection is light, you can determine an intersection point. When the thumb is pressed to move the index finger to another point, you can create an arc. How handsome is this geometric drawing board. Similarly, graph theory research on the iPad is quite convenient, allowing you to freely scale, move, delete edges, delete points, dye, undo, and other things that cannot be done with pencils or erasers. Maybe in the near future, we can hold down an edge with different sizes to change its weight.
the calculator can also be converted from a button to a blank sheet of white paper that can be graffiti freely. We can write a 32 + 23 script on the iPad, then write a = script on the back, and then write a 17 script on the White Paper; then write a sin1°≈ in another place, A 0.0174524 error is automatically displayed after the equal sign. Drag "17" to the front of "0.0174524" with your fingers, set a dot in the middle of the two numbers, or draw a cross, and enter "=" in the back. "0.2966908 will automatically appear after the equal sign. Write down (x + y) 2 and open it with two fingers, it will automatically become X2 + 2 · x · Y + y2; write down 1 + 1/2 + 1/4 + 1/8 + ..., when you fold them with your fingers, they will automatically become a 2. It's amazing to study the relationship between data and data in such an environment.
in short, the potential of the iPad does not seem to be fully explored. As a living draft, its potential is almost infinite. Of course, this is just an option, and there will be many problems in actual development. Let's wait and see what the future development of mathematical software will look like.
