as there is small change in process for ro1 ,ro2 because we don't have whole circuit and without knowing of vdd ,for finding of vds for channel length modulation ,we use different method , because there is no other method available ,for ro1and ro2 I used (va/id) which we use frequently in other transistors.also
If you have doubt at any step in the process please comment below
