Solution :
The value of Cosec 0 degrees is equal to \(\infty\) or not defined.
Proof :
\(\angle\) A is made smaller and smaller in the right \(\Delta\) ABC till it becomes zero. As \(\angle\) A gets smaller and smaller the length of the side BC decreases. The point C gets closer to the point B and finally when \(\angle\) A becomes very close to 0 degrees, AC becomes almost the same as AB, and BC gets very close to 0.
By using trigonometric formula,
Cosec A = \(hypontenuse\over perpendicular\) = \(h\over p\)
Cosec A = \(AC\over BC\) = \(AC\over 0\) = \(1\over 0\) = not defined
Hence, \(cosec 0^{\circ}\) = \(\infty\) or not defined.
