Program Explanation Given information: The value of each mass and spring constant is written below. m 1 = 1 , m 2 = 1 , m 3 = 1 k 1 = 1 , k 2 = 1 , k 3 = 1 , k 4 = 1 Explanation: The matrix differential equation for the given system is written as, M x ″ = K x Here the mass matrix M is written as, M = [ m 1 0 0 0 m 2 0 0 0 m 3 ] M = [ 1 0 0 0 1 0 0 0 1 ] Similarly the stiffness matrix K is written as, K = [ − ( k 1 + k 2 ) k 2 0 k 2 − ( k 2 + k 3 ) k 3 0 k 3 − ( k 3 + k 4 ) ] K = [ − 2 1 0 1 − 2 1 0 1 − 2 ] Therefore, matrix differential equation is written as, [ 1 0 0 0 1 0 0 0 1 ] x ″ = [ − 2 1 0 1 − 2 1 0 1 − 2 ] x Reduce the above differential equation in simplest form as, x ″ = [ 1 0 0 0 1 0 0 0 1 ] − 1 [ − 2 1 0 1 − 2 1 0 1 − 2 ] x x ″ = [ 1 0 0 0 1 0 0 0 1 ] [ − 2 1 0 1 − 2 1 0 1 − 2 ] x x ″ = [ − 2 1 0 1 − 2 1 0 1 − 2 ] x Compare the above equation with x ″ = A x , and obtain the matrix A as, A = [ − 2 1 0 1 − 2 1 0 1 − 2 ] Use calculator or matrix program to find the eigenvalues and corresponding eigenvectors for the matrix A and obtain the result as, λ 1 = − 2 ⇒ v 1 = [ − 1 0 1 ] T λ 2 = − 2 + 2 ⇒ v 2 = [ 1 2 1 ] T λ 3 = − 2 − 2 ⇒ v 3 = [ 1 − 2 1 ] T So, the displacement vector corresponding to ω 1 = 2 for λ 1 = − 2 is written as, x ( t ) = ( a 1 cos ω 1 t + b 1 sin ω 1 t ) v 1 x ( t ) = ( a 1 cos 2 t + b 1 sin 2 t ) [ − 1 0 1 ] x ( t

Problems on Growing Functions

For a given set of functions f and g, the growth of functions states that the function g grows as fast as the function f. The growth rate of algorithms helps determine the algorithm's efficiency and compare its performance to other algorithms.
