Basic Plot with Units - Problem

[wslowik]

Dear Friends,

I'm quite new in Mathcad. I have basic question: I'd like to plot a graph of sin() function. I'd like to have argument of time in seconds and return values in Volts. If I insert for X-axis (which is variable t) unit s, Mathcad automatically makes this axis unitless [(1/s) *s]. What am I doing wrong? I know that I cen generate vector o time samples t:=0s,1s..10s but I don't understand why can't I simply change units from unitless to seconds?

I attached picture.

Thank You very much in advance for help.

Best regards,

Wojciech

You never specified that t had unit time.  Mathcad will let you plot a function of an unspecified parameter, it assigns values from -10 to 10.  There's a clue:

Mathcad will force units to balance; so when you typed the s in the units placeholder, Mathcad divided it by the time default unit.

Valery defined a range variable with units:

to get his plot to work with units.

Thank you very much Valery Ochkov, Fred Kohlhepp and F.M. for your answers! Now it is clear for me that in order to work with the units I have to first define range variable, which at the same time, defines units for x-axis (in my case).

Best regards,
