Come and play with this

I am playing the game again.

Maybe someone is playing, so don't spray me,
Ah, do you know this kid shoes? Don't know, don't know, that's right (I just want to cheat on digging haha ).
Are you familiar with me?

This is wolframalpha scientific computing engine, which is unknown in the sky and in the ground.
I don't know if you can read it as "from Alpha.
As soon as he appeared. Familiar with Google, Baidu is just a float cloud in front of him.

He is not actually a search engine
Its uniqueness is that when you enter a letter, he can understand the problem immediately and give you an answer.
For example, if you say hello, he says I'm fine,
You say 3 + 2 is equal to a few. He said 5.
Well, it's a bit like artificial intelligence.
The most important thing is that he has powerful mathematical function compute functions.
According to the designer's philosophy, we can call it a "scientific computing engine". I wonder if such a concept is appropriate,

Now, let's play with it. Haha, I like this kind of stuff most.
Let's play with functions first.
Enter y = X in the text box and click the equal sign on the right,
Dangdang has everything you want to know before you:

What if you want to input a quadratic function? You cannot input the square symbol's root number. Let's talk about it now.
For example, if the 2nd power of A is entered in the text box, it will be OK if a ^ 2 is entered.
For example, input 2 ^ (1/2) in the text box at root 2.
Other complex formulas, and so on. For example, the 2nd power of the root number 9 is (9 ^ (1/2) ^ 2.

Okay. Let's verify if this is the case.
We know that the root number 2 is about 1.414. Good input 2 ^ (1/2). You don't even need to click the equals sign on the right.

We know the result is still 9. check whether this is the case.

With the input method of the quadratic function, the center of the entire circle is 0, 0, and the radius is 1.

Is it really interesting to learn mathematics like this?

It is said that this stuff has a powerful semantic parsing engine. Let's try it now.

Input: How old are you

This is not even more powerful.
You can ask how high Mount Everest is.

Input: How tall is Everest

Remind the children's shoes not to recognize all Chinese characters. Of course, Yang Wen can recognize foreign toys.
Don't worry about your poor English. You can't just get stuck in it. According to my experience, some common phrases are simple sentences and simple syntax.
As long as it is not a long sentence
This is the result of how tall is Everest:

All kinds of data have everything you need.

More powerful
You can enter where I am to query your IP address and geographical location.

You can enter how many people in America to know how many people in the United States are there, and then he will give you the answer you want just like a wise elder.

By the way, he spent a long time on his address still don't know how to pinch it is this http://www.wolframalpha.com/

Some media have said that wolframalpha is not good.
However, it turns out that wolframalpha is getting better and better.
