[SOLVED] Linear Transformation - Linear Algebra Homework Statement Determine if T is linear. T(x,y,z) = (1,1) Homework Equations Definition of Linear Transformation: A function T: R^n --> R^m is a linear transformation if for all u and v in R^n and all scalars c, the following...

Homework Statement I need to find information pertaining to the antiderivative of a function. At the moment, I just need help in finding part of the derivative: what is happening at the double root (on the derivative) I am given a quartic function labelled f' with roots at: (-5,0), a double...

I tried this equation for Monday, January 29 and it did not work. It also did not work for Tuesday, January 30 or Monday, January 01. It always comes up one day behind. Does it stop working at some year?

Here is a quick question, and it would be nice if you someone could answer yes or no. I need it to do a problem because I am unsure whether it is. The question is: Does amplitude affect the period of oscillation of a spring in simple harmonic motion? I think no because of the equation: T =...

Got It! I was able to get the answer, so you do not have to reply. I found my mistake! :)

I put my pivot point at the base of the ladder so the normal force of the floor on the ladder would be 0. The friction force would be equal in magnitude to the normal force the wall exerts on the top of the ladder. r is the length of the ladder (L) because it represents the length of the lever...

Can cosA equal Q, which is actually mu?

I need help with the following question. 1. A uniform ladder of mass M and length L leans at an angle A against a frictionless wall. If the coefficient of static friction between the ladder and the ground is Q, what is the minimum angle at which the ladder will not slip? Answer so far...

I am just learning calculus, and I have to differentiate a problem. I have worked on it and I have asked people, but they do not know. Here is what I have done thus far: f(x) = 3x-6 – 8x5 + 9x2/5 + √7 f(x) = 3(dx-6/dx) – 8(dx5/dx) + 9(dx2/5/dx) + √7(d/dx) f(x) = 3(-6x5) – 8(5x4) +...

Hello. I am currently working on a project to build a prototype concerning the topic of energy. My group has brought up the idea of developing a floor system made of piezoelectric materials with sensors to generate electricity for houses. I have been searching earnestly to find information...

I would also put a barrier to help align the laser.

I have a question concerning this question: Predict what will happen as the incident angle approaches 90 degress, and develop a method to test the prediction. I say the refraction angle would also be 90 degrees (remaining a horizontal line), so my method would be to align the laser I'm...

Hi! I need to calculate electrical energy for a project, and I have no idea how to do it. I have looked everywhere on the internet and in my textbooks, but it's nowhere. If possible, could you please tell me the formula and what the variables represent in it? That would be so amazing!

I am doing a dull vocabulary project, and I need to define impact velocity. I cannot find a suitable definition anywhere, although I have an idea. Does anyone have a good definition? My thought is: Impact velocity is the maximum velocity obtained by an object before it is stopped by something...
