Use a graphing calculator to graph Y₁, Y2, and Y₁ +Y2 on the same screen. Evaluate each of the three functions at X = 7π/6, and verify the following equality. Y₁(7π/6) + Y₂(7π/6) = (Y₁ + Y₂)(7π/6) Y₁ = cosX, Y₂ = secx Use the graphing functions of your calculator to evaluate Y₁ at (7π/6). Y₁(7π/6) = (Type an integer or decimal rounded to three decimal places as needed.) Use the graphing functions of your calculator to evaluate Y₂ at (7π/6). Y₂(7π/6) =
