 # An interesting work with numbers

So why are you giving the example that you want to use 12?

Only for radians; you can do this with degrees between -57 to 57.

It looks like the calculator is broken; in no way should arccosine return a square root.

And,

How can we draw a line whose length is equal to square root of 2.

That's interesting, but the square root of 2 is about 1.4. You might want to draw a line which length is √2 × 100 pixels.

I did something like this:

As you can see, there is a yellow, blue and white line. The white line separates the phone screen into 2 equal parts. If the width of each part is 1, then the blue line is √2.

Now, if you ignore the blue line and the white line, there is also a yellow line. The yellow line is √2 ✕ 100 pixels long.
