under THEORY OF OPERATION, formula for f given as:
f = 0.7 / RC
which is not correct.
The correct approximation formula is:
f = 1 / 0.7(RC)
which can also be expressed more simply; if harder to remember:
f = 1.44 / (RC)
I also suggest that the approximate formula for t (time) be added just prior to the calculation for frequency; as:
t = 0.7(RC)
...mentioning that R is in Ohms, and C is in Farads.
f = 0.7 / RC
which is not correct.
