It would seem that I should go back to school and repeat my assignments. This comes as a useful endeavor for repetition of knowledge and keeping the name sake. The subject of determinants at first seems mystical, and I had lost all my knowledge about this, or actually I didn't study it when I should have, so a repetition is in order.

Let us say x + y = 7.

An x-y 2D graph shows the equation's solutions as a straight line; this is a linear relationship.

Now let us say x + y = 9.

That line on the 2D graphings by definition must have an INTERSECTION point in common with the previous equation as a line because two lines on a plane must intersect, unless the exception is made where they are in parallel. So every line on this 2d mathematical plane can be represented in the terms of equations, and when the intersection point is calculated, they call this finding solutions of simultaneous equations. Amazingly this subject had me quite upset in the second or third grade or so when I was reading the Encyclopedia Britannica at home or something ancient, and in my mental fits of yelling at the book in disarray my mom called in dad to see why I was so disturbed.
I must admit I lied to dad and told him I couldn't understand how to subtract a negative from a positive. He patiently explained that thing to me about positives and negatives, but all the time I was dealing with this simultaneous equation thing, and honestly at this time in my youth, I didn't think he would understand my question, but undoubtably he would have, so I should have been truthful.

In any case I did inherit his college algebra book, and did small studies. I began with a great fascination of mathematics in general.

Sometimes, but not often dad would say what did you learn in school today? I always hated that thing where they asked you what you learned that day, because when you asked yourself that same question, you had no answer. A youngster assumes the elder knows all the answers, just watch the "Rifleman." Little Mark asked a difficult question on the show lately, but instead of repeating his question, a better one may be in order.

Pa, the teacher says that in resonance the energy oscillates between the electric and magnetic fields where .5 LI^2 = .5 CV^2. The teacher also said that when you read these amperage or voltage measurements on a meter, it just gives the average Vrms value, and that the actual peak value in time is 1.4 times the reading. Our assignment was to use a 1 amp X(C) conduction value at our supply frequency, and compare the energy transfer return the source by .5 C V^2 value with rms correction over time of frequency. But every time I do this I arrive at a figure pi times less then what it should be?

I don't know Mark, sleep on it and we will work on that thing together later if you haven't already figured it out for yourself.
