(A) Determine a specific value of A
(B) Unable to solve
(C) Infinite solutions for A
(D) No real solutions for A

Answer 1

To solve the trigonometric equation, simplify the equation using identities and then solve for A to determine a specific value.

Step-by-step explanation:

To solve the trigonometric equation cot (A+45) - tan(A-45) = 2cos A/(1+sin A), we can start by simplifying the equation.

Using the identities cot A = 1/tan A and sin² A + cos² A = 1, we can simplify the left side of the equation.

After simplifying, we can then solve for A to determine a specific value.
