Check the labels of the t's in the indefinite integral:

- the one as argument of the function v(t,...) within the integral => this one is labelled as a 'variable'

- and the integration variable t (the one following the d) => this one is labelled as an 'automatic'.

They are differently labelled, so they are seen as different variables and (only then !) the integration result makes sense.

In the other integral (not using v() but the function directly) both t's are 'automatic' variables and therefore (seen as) the same.

This autolabelling feature of Prime is often a blessing, sometimes the opposite. You can help yourself by choosing distinctive looks (fonts and/or colours) for each of the different labels to clearly show the difference between differently labelled items.

Success!

No difference in Mathcad Prime 3.1.

Thanks. But did you try it in Prime 4.0?

I really hope the next version f Prime will automatically use

"distinctive looks (fonts and/or colours) for each of the different labels to clearly show the difference between differently labelled items."

You should not need to wait for a new version of Prime. You can change the appearance yourself, see the 'Math formatting' tab.

P.S.

Ah, I see you cannot change the appearance of the 'automatic' labelled item's. Then changing the colour of the 'variable' should do it.

While you're adjusting. The International Standard ISO 80000 requires that unit names (like m, Hz and N) must be written in an upright (not italic) font.
