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 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)= -1.155. (Type an integer or decimal rounded to three decimal places as needed.) Use the graphing functions of your calculator to evaluate Y₁ +Y₂ at (7π/6). (Type an integer or decimal rounded to three decimal places as needed.)
