1. A simple probability question
X-Dragon is an interesting neutral creature in the legend of hearth stone. It cannot be a target of spells or hero skills. It has 2 blood and has good viability.

The accuracy is higher than ACOs, ASIN what.Parameters
Y
Value representing the proportion of the y-coordinate.
X
Value representing the proportion of the x-coordinate.
If both arguments passed is zero, a domain error occurs.So just remove the x=y=0 before useExample:/*atan2 Example*/#include/*printf*
Can you calculate the approximate value of x if the x power of X is 10 (see Figure 1.png)?Obviously, this value is a number between 2 and 3.Please calculate the value of X to 6 decimal places (rounded) and fill in this decimal value.Note: Only fill in a decimal, do not write any extra symbols or instructions.If X's pow
Set-x and set + x commands are used for script debugging. Set is to print the commands below it to the screen. set-x is to enable set + x, set-o is to view (xtrace), and set is to catch up with the display of a piece of code. It is valid for the entire script after the set-x
