Enter into BASIC and in immediate mode type the following code. Please. VDU 29, 639;400; MOVE -100,0 DRAW -99,-40 MOVE 100,0 DRAW 99,40 REM At this stage the two "curves" are not REM drawn symmetrically about (0,0)although their coordinates are. We continue MOVE -99,-40 DRAW -98,-80 MOVE 99,40 DRAW 98,80 MOVE -98,-80 DRAW -97,-120 MOVE 98,80 DRAW 97,120 ETC. When I try to draw my own circle using BASIC, at first glance the drawn circle may look symmetrical but on inspection it is not. BASIC's CIRCLE command does draw circles symmetrically. I used to be able to do too a long while ago but have now forgotten how. Could any one please help. Thank you. |
