No commands in C; the name of function sqrt is sqrt (include math.h; and use -lm at linkage)
square root of the argument
Java allows us to perform 'dynamic initialization' of variables too.What this means is that you can initialize variables using expressions (as will be seen in the example).In the program, we have a int variable 'root' which has an initial defined value of 10. We then create another variable 'square' of the same data-type, which will store the square of root.//This program displays dynamic initialization in javapublicclassExample{publicstaticvoidmain(String args[]){introot=10; //root has a constant value assignedintsquare=root*root; //notice that square has "root*root" assigned to it//if u change the value of root,//the value of square changes accordingly//after each compilation//display the values of square and rootSystem.out.println("Root= " +root + " Square= "+square);}}
No. The heating effect is the product of the square of the current and resistance, where the current is a root-mean-square value.A.C. current is always expressed as a root-mean-square (r.m.s.) value, which is equivalent to a d.c. current which produces exactly the same heating effect. Root-mean-square values are affected by the shape of a waveform, but not by its frequency.
For a sine wave, the RMS is the amplitude divided by square root of 2. The amplitude is 10 cm. in this case; so the exact value is 10 / root(2), or about 7.For a sine wave, the RMS is the amplitude divided by square root of 2.

double root = Math.sqrt(XXXXX); where XXXXX is the number for which you want to calculate the square root.
sudo will run a command with root privileges
You can obtain root permissions in Linux by using the "sudo" command before executing a command that requires elevated privileges. This allows you to temporarily act as the root user to perform administrative tasks. Alternatively, you can switch to the root user using the "su" command by entering the root user's password.
Either login as the root user or type: sudo then the command you wish to run.
When u put sudo before a command in terminal the command run with root privileges
The root directory is indicated by a "/'. You can navigate to the root directory using the command 'cd /'.
Enter this command as root: "apachectl start"
For Unix/Linux, use the command 'cd /' For Windows, you can also use the same command or 'cd \'
No, none of the passwords used in a Linux system can be "recovered" because there isn't a reverse encryption for it. However, you can "reset" the root password by using the single-user mode at boot time (which puts you in the root account automatically) and then changing at that time.
For Unix/Linux, use either the 'sudo' command or 'su' to the root account.
it is sqrt in header math.h
Virtually all Linux distributions will accept the "halt" command. Some also have a shutdown command, though this has additional parameters and is meant mainly to shut down the system at a certain time.
To create a new user account under any Linux distribution use command called useradd. The system administrator is responsible for creating account. Login as root user (or use sudo command).
