1st order differential equation , boundary conditions
ans = 40 ans = 450*exp(exp(20*log(log(19/90)) - 19*log(log(4/45)))) answer at t=300 must be 450 and the plot i...

1st order differential equation
Hi , the plot is still wrong , k should be get from the initial condition and the solution is y(t)=450/( e^e^(-0.02948t+0.8839)...
