Online Algebra Calculator
Many of users do not use powerful Maxima computer algebra system for systematic work, but for ad hoc algebraic calculations – equations, functions, matrixes, etc. only. To do this job, it is not useful to download the whole application from a web site.
Function: bfpsi0 (<z>, <fpprec>) bfpsi is the polygamma function of real argument <z> and integer order <n>. bfpsi0 is the digamma function. bfpsi0 (<z>, <fpprec>) is equivalent to bfpsi (0, <z>, <fpprec>).
These functions return bigfloat values. <fpprec> is the bigfloat precision of the return value.
