  • How to prove Eulers formula: $e^{it}=\\cos t +i\\sin t$?
    Euler's formula is quite a fundamental result, and we never know where it could have been used I don't expect one to know the proof of every dependent theorem of a given result

  • rotations - Are Euler angles the same as pitch, roll and yaw . . .
    The $3$ Euler angles (usually denoted by $\alpha, \beta$ and $\gamma$) are often used to represent the current orientation of an aircraft Starting from the "parked on the ground with nose pointed North" orientation of the aircraft, we can apply rotations in the Z-X'-Z'' order: Yaw around the aircraft's Z axis by $ \alpha $ Roll around the aircraft's new X' axis by $ \beta $ Yaw (again) around

  • general topology - Mismatching Euler characteristic of the Torus . . .
    You should use Euler formula on a triangulation if you want to compute the euler characteristic One easy triangulation of the torus can be obtained as following: Obtained by "discretizing a donut" Opening up the diagram one obtains (sorry for the drawing) from which you easily deduce that this particular triangulation has $9$ vertex, $27$ edges and $18$ faces
  • Connection between Hilbert function and Euler characteristic
    This is again a kind of "inclusion-exclusion" argument, and it's a useful computational tool but it doesn't by itself imply any kind of deep relationship to the topological Euler characteristic, which involves some other unrelated chain complex, with interesting homologies in higher degree but no extra grading
  • Proving that a Euler Circuit has a even degree for every vertex
    In this case however, there is a corresponding theorem for digraphs which says that a digraph (possibly with multiple edges and loops) has an Eulerian circuit if and only if every vertex has indegree equal to outdegree and are part of the same strongly connected component That theorem holds for your graph
