Plotting cosine failed, "replace complex values and NaNs by real numbers"

In attached file I'm trying to plot a function of time but am getting a "Replace complex values and NaNs by real numbers". If I include units in my "t" range definition I can plot my second function. If I exclude units I can plot my first function. But not both at same time. I can't see what is wrong.

t with unit. Then bottom plot can make.

Your range for t is defined unitless!

Thats OK with the unitless function v.AB, but in d(t) you use "d0" and "velocity" with correctly assigned units. So you have also to use a range for t with units as otherwise you run into a unit mismatch as you can't add feet and feet/seconds.

Define t:=0s,10^-6 s .. 0.01 s (you have to add a time unit to all three values).

Hi Werner,

Yes, and as you will see in my attached file, when I do define the units (exactly as you describe), then the bottom plot fails. How do I correct that?

thank you
