I'm having some difficulty understanding how to perform linear transformations on matrices. I understand the definition but not how to perform the operations. I'm going to give a few examples from my book: Suppose that T: R^2 \longrightarrow R^2 is a linear transformation such that...

The inductor capacitor circuit, commonly called a 'tank circuit' is oscillatory because the inductor charges the capacitor then the capacitor discharges and the current flows back to the inductor then the inductor charges the capacitor again until the current finally decays.

If you don't mind me asking, what types of applications did you write and for what type of businesses did you write them for. Do you think it's possible to earn a six figure salary after taxes doing freelance programming? What languages to you think are essential?

The load voltages for a parallel configuration is the same across each load. Each light in the parallel configuration has the same voltage. For a series configuration the load voltages add to equal the source voltage.

Which degree electrical engineering or computer science (programming) would be a better choice for a freelancer?

I'm having serious trouble understanding how to solve this problem using the differential equation method ( I MUST use this method). I provided the answer but my solution attempts are not producing the same result. Here is the problem...

Wow, I thought someone would understand this :cry:

[SIZE="4"]We are doing transient circuit analysis in one of my engineering courses. There are two ways of solving these types of circuits: 1. The step by step approach 2. The differential equation approach. The step by step method is well documented in our textbook, but the differential...

You have hit upon the point of my confusion exactly cristo! Jeez, so simple but I have not used this equation since precalc so i forgot how it worked! the point slope form of the line is used to find the slope of the line. It is the variable that we are solving for.

When we want to find the equation of a line we can use: Y-Y_1 = m(X-X_1) or Y = mX + B My question is aren't both equations essentially the same? For equation 1. If I know two points that the line passes through just by plugging and chugging won't that lead to what the Y intercept is...

Great Thanks a lot!

[SIZE="4"]Wow, this is a cool problem but I have no idea how to even get started. Please click on the picture to make it larger. http://img400.imageshack.us/img400/7310/homeworkzv9.th.jpg Would someone give me a hint on how to attack this problem?

Do you know of a website that demonstrates this method and lists the rules? I've googled for it but I don't come up with anything.

Yes, Please do! I actually like solving nodal/mesh equations the old fashioned way, but the professor is emphasizing this method. He said that he gets paid to show us things that are not in the textbook otherwise "we could stay home and read the d**n book and not come to class"
