## dsolve numeric substitutions...

Good day everyone,

I am writing a numerical code using dsolve which works fine but I have a challenge in inputting the previous answers in the subsequent ones. For example, how can I substitute the solutions in S1 into equ11, equ22, equ33, and equ44 in the link below?

Thank you very much as I will be expecting responses from you soon.

## How do I test against the specified tolerance?...

Good day everyone.

I am trying to write a code with variable stepsize involving tolerance. two vectors are declare for the errors. However, I don't know how to declare the two errors in comparison with the tolerance. Please kindly help. Also, any other modification to the entire code is also welcomed. Thank you all and best regards.

The code is as attached.

## How can I handle this error?...

I'm trying to solve a system of differential equations and encountered this error: Error, (in fsolve) {f1[0], f1[1], f1[2], f1[3], f2[0], f2[1], f2[2], f2[3]} are in the equation, and are not solved for. How can this error be rectified?
