Yes, it is.
Zero is rational, but it is neither positive nor negative.
That is a rational number, as are all of the integers.
It should also be a positive number. Let x be the numerator and y be the denominator. So you have +x/+y, the reciprocal would be +y/+x.
Yes, it is.
No. 0 is rational and has no reciprocal.
Taking the reciprocal (multiplicative inverse) does not affect the positive or negative status of an integer. So the reciprocal of a negative number is negative and the reciprocal of a positive number is positive. The reciprocals will be opposites (positive/negative) just as the original numbers were.
It is the positive value of that rational number.
Is '1' Any number multiplied with its reciprocal is equal to '1'
A positive rational number.
The cosecant is the reciprocal of the sine function. Now, the reciprocal of a positive number is positive, and the reciprocal of a negative number is negative.
You can multiply any pair of rational numbers as well as any irrational number and its reciprocal (or a rational multiple of its reciprocal. Thus pi * 3/7*(1/pi) is rational.
1 is the only positive number that is its own reciprocal. -1 is the negative number that is its own reciprocal.
Every positive rational number and its negative are the two square roots of the same positive rational number.
