RPN  Solve
I'm going to write about some topic here
The RPN in CAS mode is going to be implemented in the future ? The solve comand doesn't work for this http://h30434.www3.hp.com/t5/Calculators...3790#M6767 And the last thing. Is there any chance to know if theres a new calculator in the way ? Something like HP50g succesor?

RE: RPN  Solve
I believe Magnus is wondering why solve((x^26*x+(7/x)+p) = 0,x) returns empty brackets on the Prime while returning:
x = 2*(√(3*(p12))*cos((asin((3*(2*p9)*√(3)/(2*(12p)^(3/2))))/3)+(π/6))+3)/3 or x = 2*(√(3*(p12))*sin((asin((3*(2*p9)*√(3)/(2*(12p)^(3/2))))/3)+(π/3))3)/3 or x = 2*(√(3*(p12))*sin((asin((3*(2*p9)*√(3)/(2*(12p)^(3/2))))/3))+3)/3 on the tinspire cx cas. road

Algebraic extension not implemented yet for poly [1,6,p,7]", emphasis added. Perhaps a promise of future implementation? road
