Question

what can you say about cosec 0degree = 1/sin 0 degree? Is it defined?Why?

Answer 1

It is not defined as cosec 0 = 1/sin 0 = 1/0 which is undefined because this kind of division is just not defined in mathematics or if you see in books it will be given as infinity which is represented by sign "∞" .it is told as infinity as you see when you divide 1 by 0 you can never get a remainder as 0
