I can see myself as an engineering professor, author of different books and having a busy but happy life.

what does it take to be a mathematician? welcome to PF by the way,,.

wow.. nice meeting you sir! I am also interested in physics and want to know more cool stuffs about it! Welcome to PF! :)

[SIZE=16px]Where/what are R2, R1? R2 in the formula is the feedback resistor, R1 the series one.

Mr. Dave's explanation is right so I guess that settles it. I was just trying to say earlier that unlike battery, capacitor cannot be used as a first-hand source. It still needs a voltage supply. Since it filters the input depending on the other components present.

DC is only used in charging capacitor. When capacitor is put in a circuit (ex. a cascaded amplifier circuit) and Vcc will be a battery, the capacitors will be ignored in computing gain because it's in the OPEN state (I was wrong earlier, Capacitor appears as shorted in AC not in DC). Capacitors...

yup. Capacitor is shorted in DC.

battery can be used as a voltage supply in a circuit while capacitor is used to store charge in an elecrric field. However, capacifor wouldn't work if you will not use AC SUPPLY.

Isn't it chemical energy that the battery initially stores? the positive and the negative plates/terminal are being separated by some chemical paste (lead) which is electrolytic. This chemical allows electrons to pass. The potential energy that you might saying must be the energy possessed by...

welcome to PF!

trial and error of synthetic division.

Ahh.. I see. Thanks!

I've read this exact problem this morning and got 122.22. It may not be as exact as your answer but it's just the same. Just make your solution clearer to avoid confusion.

Will the prisoners be free if most of them answers correctly or should all of them answer it right?

some fractions cannot be reduced because they don't have common factors.. such fractions remain as is. Reducing fractions require practice and familiarization with numbers. If you do that, you can simplify fractions even by mere inspection.
