Q
Q: Evaluate tan^(-1)(1) + tan^(-1)(1).
Solution:
tan^(-1)(1) = π/4, thus tan^(-1)(1) + tan^(-1)(1) = π/4 + π/4 = π/2.
Steps: 5
Show Steps
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, add π/4 + π/4.
Step 5: π/4 + π/4 equals 2 * (π/4), which simplifies to π/2.
