- I`m a MAPLE user with a big problem.
- The following expression has
- zeroes at phi_d := {.9807315053, 2.160861149}.
-
- 162265091 2 446229 1/2
- (223 (- ----------- sin(phi_d) + --------)
- 4000 11
-
- 162265091 2 7689337 1/2
- + 100 (- ----------- sin(phi_d) + ---------) )
- 4000 85

- ^ 2
- Does anyone know how to find the function left after
- eliminating each pole. My MAPLE procedure fails to work properly
- even if I only wish to evaluate the value of the expression at each
- pole when the pole has been removed. Simple dividing the expression
- by an (phi_d-0.98073...) and taking the limit of the resultant expression
- as phi_d approaches 0.98703.... Doesn`t work in MAPLE either.
- Please Help.
- Yours with thanks.
- Stephen Pearce.
