What is the simplest form of 2sqrt3/sqrt6

Explanation: though it may not be a simplification, 2√3 can be shown as √12 .

We need to find the angle theta for which csc (theta) is undefined.

csc is the reciprocal of sine trigonometric function.

Therefore, csc (theta) = 1/ sin (theta).

We know sin(0)° = 0.

Let us check the value of csc (theta) by taking theta =0.

csc(0)° = 1/ sin (0)°.

Plugging value of sin(0)° = 0.

csc(0)° = 1/0.

1/0 is undefined value.
