Hello!
I have a good ole' Casio CFX-9850G PLUS, that has allways worked fine for me until recently. The problem is that it can't seem to plot sin, cos and tan graphs properly anymore. I have allways been able to do this before, but now when I try to make it draw sin x, it just draws a diagonal line. It also draws the exact same line with tan x, and it dosen't draw anything at all with cos x.

The first time it occured, I reset the memory and it worked again. However it happened again and this time it didn't work with resetting the memory.

Is there any way to fix this or do I have to buy a new calculator?

Thanks in advance!!

hi. i think your calculator is not in the Rad Mode.
for change this setting hit MENU' /> and open RUN or GRAPH by hit EXE' /> key
and inside one of them hit Shift' /> MENU' /> to open SET UP
come down to see Angle and change it to Rad (you can change this setting by hit
F1' /> or F2' /> or F3' /> ).
if these solution worked for you; reply to this post
because i have not CFX-9850G PLUS.
