I try to make a procedure for this 

Was it by a example of Riemann sum that  x-values in a array are stored for  numerical value, but in this task it seems that the array must be filled with the symbol x1,x2 , etc 

Should this be needed ?

This exact value of this serie must be calculated with help of a integral and another serie (Maclaurin)

Note: there is Taylor serie and Maclarin is a special case of this Taylor serie. 

The serie is also numerical in Maple calculated , to get a idea of the exact value

I enclosed some book taks pdf about alternating series /infinite series and products 
to get a idea what is asked for

I must program exc set 3 task 2(i) and 2(ii)

Perhaps too much asked here on the mapleprime forum to come up with the solutions for this programming task ?

I did already some investigation how the code roughly works 
 

Its a graphical programming task to let show the tread-riser outlines for a right -hand rule and mid-pointrule in a graph

I think there is a special needed package for this : student vector-calculus ?

I tried to get this plot with equal axis for x and y ? 

G:=(x,y)->2*x^2+y^2-2*(x+y+x*y-1);
implicitplot(G(x,y)=0,x=-2..10,y=-2..10,scaling=constrained);
