ඒත් ඒලෙවල් වලදි ඕනම අංශක ගාණකට සයින් කොස් ටෑන් අගයන් තියෙනව
0-360ට එනකං...

බලං යනකොට මෙතන ඇත්තටම තියෙන්නෙ ඛණ්ඩාංක තලයක්
සම්මුඛ පාද බද්ධ පාද කර්ණය නෙමේ...
Y අක්ෂය, X අක්ෂය තමා මෙතනදි සලකන්නෙ..

තව දෙයක් තමා මාපාංක. ඕලෙවල් වල මාපාංකයක් ගැන කියන්නෙ නෑනෙ..
මචං සාමාන්‍ය පෙළ කාලෙත් ඒ අගයන් තියෙනවා. අපිට උගන්නන්නේ නෑ.
