If I go to desmos calculator and type for example 5cos(45),5sin(45) a point appears at 3.5, 3.5. I want this to be a line starting from the origin 0,0 but cannot see how to do so.

I see some point options when clicking the large dot to the left of the input field but no option for a line, as in the screen shot.

How can I make this point a vector line?

    If you say $(t\cos 45, t\sin 45)$ or $(t,t)$ for that matter, you will be given a range for $t$ and a line segment whose length depends on the range of t. – user317176 Nov 02 '23 at 10:47

Two ways: 1: After the point, add t to the end. Make sure that you have not used t as a variable. Example

2 After the point, add ,(0,0), and set lines to true. Example
