Thanks for helping clear up that confusion. The problem states that the torque is constant, which implies that α should be constant, but I'm getting different accelerations at different times. I'm taking θi as 0.01 rad, with the ti as 0.1 seconds. What am I doing wrong (i.e. how do I go about...

Okay, so I've found the equation of the graph to be f(x) = x^2, as the y-values are squares of the x-values. I'm not sure where to go from here to find the angular speed and thence the angular acceleration. Any ideas?

Homework Statement The graph shows the behavior of an object with the moment of inertia of 18 kgm^2 a) Calculate the magnitude of the constant torque that acted on the system. b) Through what angle did the object rotate between t=2 and t=20 seconds? Homework Equations...

Homework Statement Find the orthogonal complement. Homework Equations span {[0 0 1 0] [2 -1 0 1]} transpose The Attempt at a Solution I'm really confused on this. I've tried setting up things like this: [0 0 1 0] [2 -1 0 1] [x y z v] transpose = [0 0 0 0] transpose But...

Homework Statement Find a basis for the subspace of R4 spanned by S. Homework Equations S: {(2,9,-2,53), (-3,2,3,-2), (8,-3,-8,17), (0,-3,0,15)} I've attempted this using a matrix and row reducing it. I'm just not sure if there's another simpler way, as I keep on getting incorrect...

Got an 88.5 % on the second exam! Spent the week/week-and-a-half beforehand studying for the exam. Hopefully I can keep up this trend, eh?

Hey All, I hope this is in the right sub-forum. As the title states, I've failed my first exam in Linear Algebra, and I'm thus in a bind. I just need some advice on how to make a come-back, as I'd honestly like to earn an A or B in the class, as it's a retake. My professor does drop an exam...
