Remove "/" bar from end of url with htaccess

Question

I wish my Url worked as much with "/" at the end as without it via htacces did so

URL FRIENDLIES

#aqui ignoramos o uso de barra no final
RewriteRule ^home$ index.php [NC,L]
RewriteRule ^sobre(.*)(/|)$ sobre.php [NC,L]
RewriteRule ^agenda(.*)(/|)$ agenda.php [NC,L]
#RewriteRule ^agenda/([^/]*)(.*)(/|)$ /curso.php?id=3&nome=$1 [L]
RewriteRule ^agenda/([a-z0-9-]+)-([0-9]+)/?$ curso.php?id=$2&curso=$1 [NC]

The problem is that this way it ignores the parameters passed in the Url.

How can I do ?
