Draw2d

Function: draw2d (<option>, <graphic_object>, ...) This function is a short cut for draw(gr2d(<options>, ..., <graphic_object>, ...)).

c(n):=(n^2)^(1/n);
sum(c(n),n,1,inf),simpsum;
sequence:makelist([i,c(i)],i,1,50);
load(draw);
draw2d(grid=true,color=blue,title="Sequence (cos(n)/n)",point_size=1,key="{a_n}",points(sequence));

It can be used to plot a unique scene in 2d.

To make use of this function, write first load(draw).

See also draw and gr2d.
