so for some assignment i found dP/dt just over two seconds of the graph, i then later use that dP/dt to multiply by dV/dP to end up with dV/dt. From there i moved the dt to the other side and integrated both sides for V = ... * t.
for this integration am i supposed to keep the integral bounds from 0 to 2, or add a constant of integration C?
so basically would it be
V=...*t + C
or
V = ...*2 - ...*0 = ...*2
pretty simple question i just dont know which to do
