Question

Can we represent -π through number line.If so how?

Answer 1

yes

Locating Pi on a Number Line A common approximation for pi is 3.14, so you could just draw a number line and label pi like this: <---|---------|---------|----> 2 3 4 ^ | pi But that shows where pi _is_, more or less. If you want to show how to _find_ it, you might do this: Take a circle whose diameter is one, and 'set' it on a number line so that it rests on zero. . . . . . . . . <---------|--------------------------> 0 Cut the circle at this point, and roll it out flat, so that one end remains at zero. . . . . . . . . . <---------|-------------------------------> 0 ^ | ? How far will the other end reach that is pi
