zero has definitions from the fields of mathematics,arms
1
[ noun ] a quantity of no importance

Examples

"it looked like nothing I had ever seen before" "reduced to nil all the work we had done" "we racked up a pathetic goose egg" "it was all for naught" "I didn't hear zilch about it"

Used in print

(Kenneth Hoffman and Ray Kunze, Linear Al...)

The projection * * f will be the identity on * * f and zero on the other * * f .

We shall find a polynomial * * f such_that * * f is the identity on * * f and is zero on the other * * f , and so that * * f , etc. .

Such an operator is obviously the zero operator ; for since it is nilpotent , the minimal polynomial for this operator is of the form * * f for some * * f ; but then since the operator is diagonalizable , the minimal polynomial cannot have a repeated root ; hence * * f and the minimal polynomial is simply x , which says the operator is 0 .

Since * * f are linearly independent functions and the exponential_function has no zeros , these r functions * * f , form a basis for the space of solutions .

(R. P. Jerrard, "Inscribed squares in plane curves"...)

As s approaches T the square will be outside C and therefore both **f and **f must cross C an odd number of times as s varies from zero to T .

From an estimated mass of 25 g for a zero magnitude meteorite , the other masses are derived with the assumption of a mass decrease by a factor of 2.512 for each unit increase in magnitude .

Note that the mass scale is one to two orders_of_magnitude greater than some previously used ; for_example , Jacchia ( 1948 ) derived a scale of 0.15 g for a * * f , zero magnitude meteorite .

(R. P. Jerrard, "Inscribed squares in plane curves"...)
