How to treat constants when solving differential equations
2018年5月21日 · I have a bit of a confusion with how we treat constants in differential equations. Typically, when solving a differential equation of the form: $$\frac{dQ}{dt} = k \ Q(t)$$ Then upon solving the differential equation: $$\int \frac{dQ}{Q} = k \int dt$$ $$\ln{Q} + C_1 = kt + kC_2$$ $$\implies \ln{Q} = kt + C $$

2) We use an algorithm to compute the exact solution of, say, linear differential equations of 2nd order. 3) This statement contradicts 1). 4) On the contrary, many problems which admit a close form expression are not easy to solve. 7) No, at best the appropriate numerical method can be very accurate. 8) What do you mean?
Solve the differential equation using Taylor-series expansion
$\begingroup$ This looks like solving using the standard series approach and isn't really utilising Taylor's Theorem to obtain the solution. This is the approach I would take to solve the problem as well since it is more general, but I don't think it is what is being asked. $\endgroup$

Is there a reason it is so rare we can solve differential equations?
2020年8月6日 · The point to make is that Differential Equations of this form are clearly just a teeny tiny small subsection of all possible Differential Equations - proving that both the solution space of Differential Equations is "much, much larger" than Polynomial Equations and already, even for such a small subsection - we begin to struggle (since any ...
