Not &quot;in stead&quot; but &quot;in addition&quot;. Through all my career I have faced various issues related to calculus, linear algebra (heck, Jacobian elimiation has its use in SAT solvers! nevermind the computer vision), strength of material (one of my bosses asked me how I&#x27;d develop more or less destructive game world) and thermodynamics (because you need that for computer hardware and hardware in general).<p>I believe that I find those problems once in one or two years. Through all my career.
