If ABCD is a cyclic quadrilateral then find the value of `sinA+sinB-sinC-sinD`

Explanation

To solve the problem, we need to find the value of \( \sin A + \sin B - \sin C - \sin D \) for a cyclic quadrilateral ABCD.

### Step-by-step Solution:

1. **Understanding Cyclic Quadrilateral Properties**:
A cyclic quadrilateral is one where all vertices lie on a circle. A key property of cyclic quadrilaterals is that the sum of opposite angles is 180 degrees. Therefore, we have:
\[
A + C = 180^\circ \quad \text{and} \quad B + D = 180^\circ
