Question

What can you say about cosec0° =1/ sin 0°? Is it defined? Why?

Answer 1

Answer:

Step-by-step explanation: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 so the quotient just goes on and on .

Answer 2

Answer:

cosec theta=1/sin theta

So it is undefined whenever sin theta is 0

So x=n* pi does not lie in it's domain.

put n = 0. even x=0 does not lie.
