1. Question 1

   Q1. What is the value of tan(A + B) in terms of tan(A) and tan(B)?

   • A) (tan(A) + tan(B)) / (1 - tan(A) tan(B))
   • B) (tan(A) - tan(B)) / (1 + tan(A) tan(B))
   • C) (tan(A) + tan(B)) / (1 + tan(A) tan(B))
   • D) (tan(A) - tan(B)) / (1 - tan(B) tan(A))

   Answer: (tan(A) + tan(B)) / (1 - tan(A) tan(B))

   Explanation: Using the sum formula for tangent, tan(A + B) = (tan(A) + tan(B)) / (1 - tan(A) tan(B)), derived from sum and difference identities.
