So it is still a waste of time to do much of it by hand. Much of the complex problems will be solved in finite element analysis. A lot more focus should be on how to properly model a problem. I find few good examples on how to model complex situations in physics, there are too many shortcuts in my physics book like short angle approximation, infinite lengths, and using circles rather than any other function for a curve, just because it's easy to do the integral.
