My ODEs textbook uses both graph and plot but I can't figure out how it chooses one over the other.
From the book:
Sketch the graph of the solution in the x1x2-plane for t ≥ 0.
[this one was referring to a continuous function]
Also from the book:
Plots of the solution and a tangent line approximation for the initial value problem (11).
[this one referring to a continuous solution]
Is there a formal, to some degree, distinction between the two terms? When do I call it a plot and when do I call it a graph?
