This is Peter Bengtssons site about science and especially chemistry, mathematics and physics.

This Month I've put in some links for those of you who has CASIO calculator I have a model called CASIO fx-9700GE A funny thing you can do with your Casio calculator. You can paint a flower very easily. Here it is:
Go to "COMP" menu 1; Press "SHIFT", "MENU"; Make sure the arrow is on "GRAPH TYPE" (I think it's already on "RECT"), now press "f2" where it says "POL"; Now it's suppost to say "GRAPH TYPE : POL"; Press "EXIT"; Press the button "Graph" (so it says "Graph r="); Then type in: '4sin +3(0 with a line through, two buttons above 7); "EXE"; Now try to change the numbers in the formula and see the differnce.
