I tried using The Sum that E for lists with i=0 and infinity sign above and the expression after the = sign.
I put the template on my Home page and added all the parts it did not work.
Does anyone know how to use it
Solved! Go to Solution.

Hi!, HeyJoeJoe :
Try, with ... sin(PI/2)=Sum(((-1)^i*X^(2*i+1))/(2*i+1)!,i,10,infinite) --> X=~ 8.73894

Hi!, @HeyJoeJoe :
The result in Exact Mode, of you ultimate equation is, with Wolfram Alpha ...
sin(pi/2)=Sum(((-1)^n*x^2*n+1)/(2*n+1)!),n,10,infinite) =~ -2.32518 x10^8 = complex infinite
In HP PRIME calculator ...
