Solution to the differential equation in the "Trends not considered in this course: Physics-informed neural networks (PINNs)" in the ml_cfd_intro

[SoufianeAitlhadj]

I think that the solution of the diffrential equation : $$ \frac{\mathrm{d}x}{\mathrm{d}t} = -kx\quad \text{with}\quad x(t=0)=1\quad \text{and}\quad x\in\left[0, 1\right]. $$ has to be : $$ x(t) = \mathrm{exp}\left(-kt\right). $$ not $$ x(t) = \mathrm{exp}\left(-kx\right). $$ since the solution has to be a function of time t.
