Vc=〖Vs(1-e〗^(-t/RC)): how to make t the subject of the formula?

[AdilSaumtally]

I have an equation for the voltage across the capacity (as a function of time t) and trying to re arrange the formula to make t the subject.

I have a result of:

-RC*ln(Vc/Vs) = t

is this correct?

This is not a C/C++ question, your thread has been moved to the algorithms forum.
