I'm wiling to teach you what you'd like to learn. All I need from you is the specific question you'd like to be taught how to answer. I'd also recommend sharing what you currently understand about the topic, to take an active role in learning it, and so I know where to direct my attention to help you understand.
As an example, suppose you are given this sine wave graph:
You might have a question asking you to find a time instant when the voltage equals half the maximum voltage. Suppose you are given units of Volts on the vertical axis.
You might be thinking, "I can see that its period is 2 seconds, and that its amplitude is 2 Volts. I know this means that I'm looking for a point where the voltage is 1 Volt. But how do I build the equation of the sine wave, and reverse it to solve for time?"
