The following are all angle measures (in degrees, rounded to the nearest tenth) whose tangent is -16 . Which is the principal value of arctan(-16) ? Choose 1 answer: (A) -626.4^(@) (B) -446.4^(@) (C) -266.4^(@) (D) -86.4^(@)

Principal Value Range: The principal value of an arctan function is the value of the inverse tangent that lies between -90 degrees and 90 degrees.Calculate arctan(-16): To find the principal value of arctan(-16), we can use a calculator or a computer to compute the inverse tangent of -16.Use Calculator: Using a calculator, we find that arctan(-16) is approximately -86.4 degrees.Verify Principal Value: The principal value of arctan(-16) must be in the range of -90 degrees to 90 degrees, and since -86.4 degrees falls within this range, it is the correct principal value.
