Need Help With Graphs!

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
![<span class=](/dot/public/style_emoticons/default/MENU.jpg)
![<span class=](/dot/public/style_emoticons/default/EXE.jpg)
and inside one of them hit
![<span class=](/dot/public/style_emoticons/default/SHIFT.jpg)
![<span class=](/dot/public/style_emoticons/default/MENU.jpg)
come down to see Angle and change it to Rad (you can change this setting by hit
![<span class=](/dot/public/style_emoticons/default/F1.jpg)
![<span class=](/dot/public/style_emoticons/default/F2.jpg)
![<span class=](/dot/public/style_emoticons/default/F3.jpg)
