I think Denaya’s comment is correct, because the Calandra method is always based on finding a number that has nearest square but still smaller than the number that to be calculated it’s square root. So, for square root of 4, the Calandra method yeilds 1.999999… not precise 2.

Denaya, 4=2*2, so mr.Dave need not Calandra method to calculate the square root of 4, coz it is equal 2, isn’t it?.

Of course @Dave, like for pi number we are imposible to write square root of a number in fractional form. Denaya believes Dave still remember that world has Calandra method as the simpliest method for calculating square root. Unfortunately Calandra method is still difficult to get the root of 3, even it can’t gives the root of 4.

root 3 can be proved to be irrational so im unsure what you mean by getting the value of root 3 as it cant be written as a fraction or finite/recurring decimal.

though I would be glad to help
dave,

Apologise Mr.Rohedi, Denaya is now more interested to the expression of √3, cos we’ve just celebrated the square root day on 3/3/9. Would you help @Dave in getting the value of √3 by simple way?

Excelent explanation, but it is still to be stressed that basically the moment is defined as the multiplication between a force with it’s lever respect to the pivot point. By this definition, the readers understand why both of sine and cosine functions can involve on the moment expression.
