Not if your goal is to fly to London.but if your goal is to build a plane that can fly to london,now that's a different thing.and there's no math in there.

yes but i haven't done many.that's where your help part comes in.

i know how to find e.i. the Maclaurin series for sine,cosine,exp functions,but not for tangent,cotangent,sin(x)e^x,etc.
