>tfw your solver finds a solution to your system of ODEs after trying everything, but suddenly works for some reason because you changed some insignificant thing for some reason

I literally typed a minus sign into a sqrt() and then deleted it again. Feels good man.

d(F_A) / d(W) = r_A
F_A(0) = 2.2017
d(F_C) / d(W) = r_C

d(F_D) / d(W) = r_D
F_D(0) = 0
r_A1=(-1*15*0.05*C_A*0.008*C_B)/(1+0.05*C_A)
