We do study DC Analysis first before AC Analysis for the sake of simplicity, for pedagogic reasons, and also for historic reasons. As useful and as easy to understand as DC is, it serves as a preparatory ladder in studying the more complex behavior of AC. In addition, it is to respect the historical sequence of events since DC sources were first discovered before the AC sources.
ac passes by repeatedly charging and discharging the capacitor. when you study ac circuit analysis, you will find out about impedance and reactance, which will allow you to compute how ac behaves in capacitors and inductors.
ac transient analysis is frequency domain analysis.
You need to keep track of phase angle in AC, but not in DC.
1)ac analysis 2)dc analysis 3)transient analysis
For calculations Peak or magnitude is used.

I believe it means Before
DC Analysis: For this analysis, frequency is made zero and the voltage of the source is increased in small steps from 0V.And the output voltage is plotted. So, finally we get a Vout vs Vin curve. AC Analysis: In this analysis, we choose an AC source. We keep the Offset voltage = 0V, AC voltage or small signal voltage = 2V (You can take any voltage you wish and it doesnt matter). So, to plot the ac response or frequency response of the circuit, increase the frequency in steps and note the output voltage. from this analysis , we can find the gain of the circuit over frequency.
AC analysis is philosophically the same as DC analysis. You use Ohm's law, Kirchoff's voltage and current laws, and Norton and Thevanin equivalents, to progressively analyze each component of a circuit until you know everything about all components. The difference between AC and DC analysis is that you need to consider reactive loads, such as capacitors and inductors, which have a time-varying response to a change in state. This makes analysis more complex, but the basic rules are the same - you just can't use steady state techniques.

ac is After Christ and bc is Before Christ
