=x, then the value of x is:

  1. A
    cscA+cotA
  2. B
    cscA−cotA
  3. C
    csc

    A
  4. D
    csc
    2
    A+cot
    2
    A

Solution & Step-by-step Explanation

We know the standard trigonometric identity:
csc
2
A−cot
2
A=1
This can be factored as:

(cscA−cotA)(cscA+cotA)=1
Rearranging the terms:

cscA−cotA
1

=cscA+cotA
Therefore, x=cscA+cotA.
