    Comparing KE of Electron & Alpha Particle w/ Same R of Curvature

    Homework Statement Suppose that I want to compare the Kinetic Energy of an electron to the Kinetic Energy of an alpha particle if they both have the same radius of curvature in a magnetic field. Homework Equations qvB = mv^2/r KE = 1/2 mv^2 The Attempt at a Solution I am...

    Quadratic Interpolation question

    I have to find a system of linear equations to determine a quadratic polynomial p(x) = ax2+bx+c Given the conditions: p(1) = f(1) p'(1) = f'(1) p''(1) = f''(1) where f(x) = xex-1 I know: p(x) = ax2+bx+c p'(x) = 2ax +b p''(x) = 2x f(x) = xex-1 f'(x) = ex-1 +...

    How can I reduce this matrix to its reduced row echelon form?

    I have to produce the reduced row echelon form of the following matrix: A = | cos(x) sin(x) | | -sin(x) cos(x) | I am just learning Linear Algebra, and I am in the early Chapters of my book, so I can only use the Gauss method or the Gauss-Jordan method for...
