Hi,

I'm trying to do a simple line intersection experiment in Geogebra, but I'm struggling with functions which take vectors.

Even when I'm trying something extremely basic, like this function to get the x component of a vector:

f(V) = x(V)

I get the following error:

Illegal argument
x(V)

How can I take vectors as function parameters? I don't feel like I'm trying to do something remotely complicated here, I must be missing something.

I started using Todoist a ~month ago, and it's nice enough but I don't understand how I'm supposed to deal with notifications.

I don't have many scheduled items in Todoist, meetings etc end up in my calendar so most tasks end up unscheduled. But I have added some tasks to be done on specific days.

I want a notification when I have an item due. But I don't want the daily "You have no tasks scheduled for today" notifications when I haven't scheduled anything. This seems like a pretty common use case, but I don't understand how to set the notification settings up this way?

In fact, I just found out I forgot an item a couple days ago because I've been ignoring the daily "You have nothing scheduled for today" notifications and therefore ignored it when it said I had an item as well.
