There is one way of remembering the signs of the octant.... Starting from 1-4 octant the x -y axis are same that of 5-8 octant... Now looking at the z-axis the first four octant are positive i.e ( first floor) and from 5-8 are negative (ground floor) . Instead of remebering the diagram , TRY THIS METHOD.. 😁😁✌

if u have problem to learn the picture or in sign than u can also make this picture with the help of 3 pens....first put 2 pen in + position with your hand than put 3rd pen horizontally as X axis and try to hold in a way that caps of your pen lies on a 1st octane and caps are the sign of positive axis or + sign........i hope it will help u
Thank u so much mam 😊 It was the hardest chapter for me to understand but u made it a cup of tea 😌😁💯💯
This video is literally amazing......perfect explanation which clears all the concepts within minutes........I would really like to thank u mam for such wonderful explanations......(p.s. your method of clearing the concepts using day to day examples is the best way as we can totally relate to it)
