Rehkha from 5 Bakawali 2012 has done this presentation on steps involved in calculating the gradient of a slope. Thsi question always comes out in Paper 3 ( 3 marks) and in Peka . It also occasionally in Paper 1 and 2.
I am trying to upload Rekha powerpoint - I hope it succeeds.
There is always room to learn through trying out something new.
Congrats Rekha for doing a great pience of work.
Love
Pn Tan
