Problems with displaying my graph in Mathcad

[mechanicaljw]

Hello All,

I am new to Mathcad and when i try plotting certain functions, it is not working. The graphing area is red and the following message is what I am getting: "All evaluations resulted in either an error or a complex results". I want to see the zeros of the function in the plot. In one such case I plotted the same function that Mathcad would not plot using gnuplot and it worked. Eventhough the graph is not displaying in Mathcad, when i find the zeros, Mathcad is giving me the correct results. Any idea what I might be doing wrong?

Thanks!
Jimmy

Hi All,

I just deleted the previous graphs that were not working and replotted and it now works. Not sure what was wrong though.

Thanks!
