Questions & Step-by-Step Solutions

What is the value of tan^(-1)(1) + tan^(-1)(1)?
Correct Answer: π/2
  • Step 1: Understand that tan^(-1)(1) means the angle whose tangent is 1.
  • Step 2: Recall that the angle whose tangent is 1 is π/4 (or 45 degrees).
  • Step 3: Since we have tan^(-1)(1) + tan^(-1)(1), we can replace each tan^(-1)(1) with π/4.
  • Step 4: Now, we add π/4 + π/4.
  • Step 5: Adding π/4 + π/4 gives us 2 * (π/4) = π/2.
