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);}}
RMS stands for root mean square. This is done so that negative values are then treated as positive values. In AC power for example, the voltage varies between a negative and a positive value. The number is squared and then the square root of this value is taken and the mean (average) of these numbers gives the answer. For example -40 is squared to become 1600 and then the square root of 1600 is taken to become 40 (a negative number becomes a positive number).If this wasn't done then the average value of AC power would be zero.
square root of the argument
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.

The square root of a real number is not always positive. The square root of any positive number is positive, the square root of zero is zero (not positive), and the square root of a negative number is complex (i.e. neither positive nor negative). The square root of 16 = -4 or 4. The square root of 0 = 0 The square root of -16 = -4i or 4i
+6 is the positive square root of 36.
The positive square root of 289 is 17.
It is the same as finding the square root.
The square root of a positive number results in a positive number. For example, the square root of 25 is 5. * * * * * Not true! There are two real square roots for every positive number: one positive and one negative. -5 is as much a square root of 25 as +5 is. However, the positive root is the principal root and so is often presented as the only root.
the principal root is the positive square root.
Positive Square root of 7.3441 is 2.71
√(a^2) That is |a| (the absolute value of a) Because if a is positive, a^2 is positive, and since √ is a positive square root, √(a^2) is a. If a is negative, a^2 is positive, and since √ is a positive square root, √(a^2) is -a. So if a is positive, √(a^2) is positive (which is a) If a is negative, √(a^2) is also positive (which is -a) So √(a^2) is |a| for every a.
A positive number has two square roots, that is, there are two solutions to an equation like x2 = 100. The "principal square root" refers to the positive solution.
The principal square root is the non-negative square root.
The square root of 6724 is 82
Every positive integer has two square roots, a positive square root and a negative square root. This is because, just like a positive number multiplied by a positive number is equal to a positive number, a negative number multiplied by a negative number is equal to a positive number. Therefore, rounded to two decimal places, the positive square root is equal to 7.28, and the negative square root is -7.28.
