Hello everyone!
Today, I started writing my code on design of stair slab ques no.6 of https://hsrai.gdy.club/hrb/DA/PDF/DA.pdf . It was quite easy to start as firstly we need to calculate depth and then loads in the flat portion. I faced some errors due to brackets. And my next step is to find z by using cos(a) and tan(a), so i searched how to write them in octave. I saw some programmes on that and at the end of the day, I was able to calculate the value of z.
