I know it is important to understand how things work on the mathematical level. It is just that in all of his other lectures, he does a great job on showing us the intuitive solutions, but in this one he doesn't. It is like he has neglected to show us how a capacitor works in a circuit by looking at it intuitively. For all other componets he has done just that, but not for the capacitor. That is what puzzles me.
It's not always just because it's easy to understand intuitively that you should not show where it comes from. Not everyone like an equation just give to them without a derivation or proof even if it's intuitively.
Also, in alot of courses knowing where something comes from helps you understand the limits of the equation and when you can no longer use them. As an engineer you can't always just blindly use equations without thinking wether or not you're allowed to use them.
I don't understand why he doesn't show the intuitive way of sovlving this problem. To me it is quite obvious that the amplitude falls as the frequences get higher. That is simply the way a capacitor works. It blocks low frequences and lets high frequences pass through, thereby leading the current away from the inverter to ground. No mystrery in that.
