Typo in Chapter 1

[rk-mlu]

Dear Dr. Sundnes,

I found a minor typo in Chapter 1:

solving_odes_in_python/book_src/chapters/chapter1.do.txt

Line 58 in 21b2caa

Specifying an initial condition $u(t_0)=u_0$ gives $C=u_0$, and we get the unique solution $u(t)=u_0e^t$.

In this line, the initial time t_0 is still generic. However, the solution u = C e^t with constant C = u_0 requires t_0 = 0. Alternatively, the general solution is u = u_0 e^{t-t_0}.

Best regards,
Raphael Kruse
