# Radians: marking and using in graphs

Trying to make this great activity that DESMOS have created into an activity that uses Radians.

I’ve tried to edit it for myself but looks like I may have just made more issues for myself.

I haven’t quite finished making all the slides but if I can get this much to work I can hopefully finish it myself.

Any help is very much appreciated.

I’ve had a look through and tried to guess what issues you’re encountering, but if you could be specific about what you’re struggling with we might be able to help further.

Things I’ve spotted…
On slide 1 (the table):

These would need to be

\frac{\pi}{2}


etc. in order to work correctly.

On slides 5 and so on:

You probably want to remove the degrees symbol as the angle is now in radians. You’ll need to adjust the 270 to be the equivalent radian value - or might need to allow a little margin of error, for example:

a=c3graph.number("a")
correct: a>4.712 and a<4.713


and in the graph itself, for the reveal animation to work correctly, you need to swap the 360 in b out for 2pi:

Hopefully that points you in the right direction, but please do let us know if there’s anything else you’re not sure how to fix.
