blackstreet23
  • blackstreet23
the problem is that i dont get the same answer to two decimal places
anonymous
  • anonymous
Wait what answers are you getting?
anonymous
  • anonymous
I got precisely the same answers and check u used the right series.... seems right to me
anonymous
  • anonymous
Using the Mcclaurin series that is
blackstreet23
  • blackstreet23
but it is not right to 3 decimal places
anonymous
  • anonymous
what answers are you getting please?
anonymous
  • anonymous
I got .3805... for both the mcclaurin series and actually putting in tan^-1(0.4) in my calculator
blackstreet23
  • blackstreet23
ohh yeah I saw what was my problem
blackstreet23
  • blackstreet23
I had it in degrees instead of radians :/
anonymous
  • anonymous
:D yea i figured that was probably the problem... next time just post your answers and I would've known immediately Specifically from the fact that the result of arctan has to fall between -pi/4 and pi/4 meaning the degress answer is way to large to possible be the answer
anonymous
  • anonymous
This is due to the fact that tan(x) has singularities at those points.... hence arctan's range -1 to 1 corresponds to that
anonymous
  • anonymous
Ok so it looks right to me are you happy do you get what is going on... have any other questions about it?
blackstreet23
  • blackstreet23
no. Is ok thanks :)
blackstreet23
  • blackstreet23
