# Possible to apply a function without brackets?

I was just playing around with entering two dimensional forms of some expressions. As an example, I wanted to write Integral[Cot[t],t]. I got as far as \[Integral]Cot[t] \[DifferentialD]t.

But I would love to make it look even more natural by omitting the brackets around the t. Is there any \[] character that helps me do that?

Looks like you can use \[InvisibleApplication]. It's probably also worth knowing \[InvisibleComma] when writing expressions this way.
For example in your case: \[Integral]Cot\[InvisibleApplication]t \[DifferentialD]t
This bit me once... see this question that I asked (also the very first question on this site). You might also find \[InvisibleSpace], \[ImplicitPlus] and \[InvisibleTimes] useful if you choose to go this route, but be aware that these might make it very hard to debug and make it less readable for others. –  rm -rf Jul 19 '12 at 1:35
@R.M Have you ever figured out what \[ImplicitPlus] is used for? –  sebhofer Jul 19 '12 at 8:42
@sebhofer, Wolfram's example is 9\[ImplicitPlus]3<Ctrl-/>4 for 9-and-three-quarters written in its traditional numberical form. –  sblom Jul 19 '12 at 16:34
