Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I am having a terrible time trying to plot a function in Mathematica that is evaluated to have parts like: Cos(1000t+0.0i)

When I try and plot it against t, it says that the function is not machine size at many values of t.

I can't understand why Mathematica is putting 0.0i in there and secondly why it thinks that 0.0i means it can't plot the function. Takign the Re[function] does nothing either.

There surely must be a way of changing MachinePrecision or FindRoots or something that can eliminate this 0.0i? I really can't understand why Mathematica has such a stupid output for a function that is clearly real.

There was a second problem, much less substantial; I want to play a sound without producing a graph of the signal, is this possible?

Big thank-you for anyone who can help,

Natski
