there was another answer, but i did not quite get it. it seemed to use polar coordinates or something, but i don't really understand how it set up the integral.

I have first considered an elementary ring of the charged disk
then we find electric field due to this ring at its axis from its
center at a distance z.We then used technique of
integration to find E due to whole disk.
