# Cannot Scale Integral Symbol using scaleobj [closed]

Hi I'm try to reduce the size of my integral sign so it fits within the same line as the rest of my equation. I tried using scaleobj to reduce the size, but I cannot figure out why I'm getting an "undefined control sequence" error using the following:

$$\displaystyle V(t) = \cos{(\omega_{c}t}+k \scaleobj{.2}{\int}f(t)dt) \label{fmmod}$$


How am I using \scaleobj incorrectly?

• as always on the site please provide a full (but minimal) example, not sniplets. Where does \scaleobj come from? Additionally \displaystyle does nothing here as you are already in display style – daleif Apr 1 '20 at 13:02
• I'm voting to close this question as off-topic because the problem was solved by adding a necessary package. – barbara beeton Apr 1 '20 at 16:19
