ArcCos

  • ArcCos[ z ] gives the arc cosine of the complex number z.
  • Mathematical function (see Section A.3.10).
  • All results are given in radians.
  • For real z between and , the results are always in the range to .
  • ArcCos[ z ] has branch cut discontinuities in the complex z plane running from to and to .
  • See the Mathematica book: Section 1.1.3Section 3.2.6.

    This is an indefinite integral.

    In[2]:=

    Out[2]=

    This gives a power series expansion about .
