What's a good solution if I'm looking to cross out an entire row or column in a matrix or array environment? I'm trying to better visually describe the process of expansion by minors to calculate a determinant, which involves "deleting" entire rows and columns of a matrix. Thank you in advance!

I remember a slightly different notation for the line integral [1]. With your notation you could run into trouble when it comes to calculating the line integral for a closed curve.

However, the command definition is the important part here. That is to say the sequence of the stuff you put in. The ...

Hey guys,

I just recently defined the following command called \Cint which features an integral sign with a C overlayed (I want to convey a line integral over curve C).

\newcommand{\Cint}{\mathrlap \int \hspace{1.1px} C \ }

Unfortunately, when I try to put limits on the integral, I find that it ...

you could use the command \displaystyle before the integral.

I've tried that, but unfortunately TexMaker gives me a "Bad math environment delimiter." error D:

If I am making an array in LaTeX, and I want to put integrals as entries in the array, the output I get is the inline math height integrals. What code do I need to add so that the integrals come out full displaymath height? Thanks!!
