Hello, I am having a lot of trouble with Mathematica since several weeks. When I ask it to plot an expression, nothing appears. But when I use the automatic function "plot", then it does it by including invisible parameters: Manipulate[ DiscretePlot[ 1/2 (-1 + k)^ L k^(-2 L) (-.1d (-1 + k)^(-1 + L) + (2 k^L (-1 + (k/(-1 + k))^L))/L) V, {k, 1, 20}], {.1d, 1,20}, {L, -2, 2}, {V, -2, 2}]
Also, the program treats numbers as variables, and then plots them, like this:
Plot[(16 .1d)/729, {.1d, -8, 8}]
Can someone help me, I have no idea what is going on. Thanks
