Question #1ed3f

Answer 1

No

Explanation:

Given is the expression
`1/sin 0`

We know that `sin0=0`,
Therefore, the expression reduces to `1/0`
We also know that division by `0` is not defined.
Hence, we should say
`1/sin 0="undefined"`.

If a graph is drawn for `1/x` as shown below, there is a discontinuity at zero.

As for very small negative numbers, `1/x` approaches negative infinity, and for very small positive numbers, `1/x` approaches positive infinity.
