If you click a curve or expression, you'll see gray dots appear at interesting points including maximums, minimums, intercepts, and intersections. Click on a gray dot to open the coordinates at that point - click the point again to hide the coordinates.
You can also trace along a function by clicking and dragging along the curve.
Good. But I would like more choice in the "points of interest."
You can print them but you cannot see them when you export it as an image. And choice of points would be great too: you can do that with table but they will be without coordinates.
When I copy paste the image, I need certain points to be labelled. how can I do it then?
I am trying to make a graph that takes 3 points and creates the circumcircle of the points, however, I am not able to get the x and y values for the circumcentre, is there any way I can plug the coordinates to create the circle without having to manually do it each time?

I found a points of interest glitch:
@mATT C; Looks pretty interesting to me. XD haha, strange that it's similar to a sin wave, but it looks like it's just a clip issue with massive numbers. Javascript has it's limits.
@Anshul: Points of interest are not necessary. It's complicated and ugly, but there is a way to get it: https://www.desmos.com/calculator/sdql5jofvd
@Anshul and @Colegaynor; On the contrary, obtaining the intercepts of two linear equations is quite simple (and clean too!). It uses the substitution method with a little mixing around. I whipped up this small graph to demonstrate:
