Question

if cosec theta is 0.5 then what is the possible value of theta​

Answer 1

Answer:

cosec a=0.5

we know that :-

0.5is equal to the 60° and π/3.

so cosec a =0.5

cosec a =60°

a=cosec 60°

a=2/√3

Answer 2

Answer:

cosec(theta)=0.5

either cosec ( theta)>=1 or cosec (theta)<=-1

so, cosec( theta) =0.5 is not possible

another way to solve this question

cosec( theta) =0.5 means sin( theta) =2,which is meaningless as

-1=<sin(theta)=<1
