  why does tan(-120) = - 0.71312301
  
  and not sqrt 3 ?
  
  I tried making a graph and still came up with sqrt 3??

  2. tan -120 = (sqrt(3)) = 1.73205
  coterminal with 240 deg in QIII so positive
  
  reference angle is 60
  
  Where did you get - 0.71312301
  Are you using a cal. set to the wrong setting, rads vs degrees?

  3. I used a calculator to check my answer, (which was originally sqrt 3) and then on the calculator I got 0.713... so I was confused ... anyway thank you

  4. also, for even vs. odd functions it saids that tan(-angle) = - tan(angle)
  
  so that doesn't matter since tan is positive in the QIII?

explanation: The document contains a math question and an answer to this question. The question is about the value of tan(-120) and why it is not equal to sqrt(3), but instead approximately -0.71312301. The user also asks what 0.71312301 would be as a square root and discusses the concept of even and odd functions in relation to the tangent function. The answer provided explains that tan(-120) is equal to sqrt(3) when calculated in degrees, and suggests that the discrepancy might be due to the calculator being set to the wrong mode (radians vs. degrees).
