Which one should I use?
I got a 34 on the ACT Math section and a 32 overall score on the ACT.
I would go with Degrees setting unless you’re asked to identify the graph of a trig function. Then, you would use radians because the degrees setting will cause the trig graph to become a straight line (which you don’t want).
Hope this helps and good luck!
Pick one. If you need to use the other, just multiply the argument by 180/pi or pi/180.
Towards the beginning, the questions usually involve degrees. Towards the end, the questions usually are in radians.
