When given y'' + ay' + by + c = 0 The characteristic equation is: λ^2 + aλ + b = 0 Now I'm making a substitution of e^(λx) to get [(λ^2 + aλ + b)][e^(λx)] = 0 double root : [(λ - alpha)^2] [e^(λx)] = 0 My question now is that if I were to do the same thing with the...

What to expect from my class "Theoretical Physics 1"? I'm starting my major in physics this fall and I'm taking multivariable calculus, mechanics, E & M, and theoretical physics 1. I pretty much know what to expect from the other 3. But I'm going into this class "theoretical physics"...

If I major in physics and minor in math at university how much free time will I have? Because I want to dedicate myself to piano just as much as school. This whole university thing is scaring me. It makes me feel like not going at all and just playing the piano instead. Although I do have...

I applied to Concordia University and Mcgill University in Montreal, Quebec. I already got an acceptance letter from Concordia I was wondering if it's a good idea to study physics at Concordia. I don't really know much about universities to begin with nor do I care that much but if I'm...

I don't understand the theory as much as I would like to. Please pardon my non technical vocabulary and lack of thorough insight on the topic at hand. So...geez how do I put this into words...So everything imaginable in this universe was compressed, (superimposed?), into what is popularly...

It must be refreshing to live in a small town for a while.

Thanks for the replies. My teacher uses this method and calls it row augmentation. Pretty much if he has a 3x3 matrix he'll make either any row or column a value followed by zeros by adding some other row to it or some column. It's hard to explain but say row 1 is 1 2 3 he'll add say row 2...

Hello, I just finished doing a question in which I had to find the values of x y and z from 3 linear equations using Cramer's rule. I used row augmentation for the x and y but then for z I couldn't see any way of using row augmentation. So I looked in my notes and saw an example using...

is it E line=(K)(2)absolutevalue(lambda)/r ? =(k)(2)absval(Q/x)/r

Homework Statement What is the electric field strength at the center of the triangle? Three 13.0 -cm-long rods form an equilateral triangle. Two of the rods are charged to + 19.0 nC, the third to - 19.0 nC . What is the electric field strength at the center of the triangle...

Thank you! That worked perfectly. I understand where I made my mistake now too.

A little bit off the debate, but I am a student of Dawson College and I felt like sharing my experience. It was one of the scarier moments of my life to know someone was on a shooting rampage and at any moment I could have found myself face to face with a killer while running out of the school...

I tried to work out this problem a few different ways but I never get the right answer. A block hangs in equilibrium from a vertical spring. When a second identical block is added, the original block sags by 8.00 cm What is the oscillation frequency of the two-block system? What I've...

When I say pure science I'm trying to distinguish between physics- which I imply is the pure science despite the possible fact that it may be incorrect to use the term the way I did- and a social science like economics for instance. What do I expect hmm... a lot of mathematics courses to...

I don't know why I wrote pure infront of it. Maybe I was going to write pure sciences but then wrote physics by accident. Anyways I just simply mean physics.
