Or just open any spreadsheet program and make three rows.

Row 2 column A write Frequency Column B (square 2B) = Lowest frequency of interest in cycles i.e. 2.
Row 3 column 1 write Capacitor Value= Column B (square 3B) cut and paste the following formula +1000000*((1/B2)/(2.828*B1*1000))

I have all my formulas in this way. I sell you my computer for £1,000. How you think I bang out facts so fast? Don't need five pages of discussion to design my amps. just a quick tip.

I make my own from the facts published in text books which have passed peer review editorial checking and have become known reliable electronics sources for their era. Not the self praise of some internet wannabe.
