What are some examples of a fraction but not a rational number?

A rational number is a fraction with an integer in the numerator, and a non-zero integer in the denominator. If you consider pi/2, pi/3, pi/4 (common 'fractions' of pi used in trigonometry) to be 'fractions', then these are not rational numbers.

When cosec is positive?

Between (2k)*pi radians and (1+2k)*pi radians where k is an integer. If you are still working with degrees, that is360*k degrees to (1+2k)*180 degrees, for integer values of k.NB: these are open intervals: that is, the end points are not included.Between (2k)*pi radians and (1+2k)*pi radians where k is an integer.

Can the quotient of two irrational numbers be rational?

Yes. 2*pi is irrational, pi is irrational, but their quotient is 2pi/pi = 2: not only rational, but integer.
