Math Calculus EBK DIFFERENTIAL EQUATIONS

Program Description: Purpose of the problem is to obtain the particular solution of the differential equation y ″ + 9 y = 2 sec 3 x by the method of variation of parameter. Summary introduction: Problem will use a variation of the parameter method for the non-homogeneous equation y ″ + P ( x ) y ′ + Q ( x ) y = f ( x ) which has a complementary function y c ( x ) = c 1 y 1 ( x ) + c 2 y 2 ( x ) . The Wronskian of two independent solutions y 1 and y 2 of the associated homogeneous equation is W = W ( y 1 , y 2 ) and a particular solution of the non-homogeneous equation is y p ( x ) = − y 1 ( x ) ∫ y 2 ( x ) f ( x ) W ( x ) d x + y 2 ( x ) ∫ y 1 ( x ) f ( x ) W ( x ) d x .

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.

Question

Chapter 3.5, Problem 53P

Program Plan Intro

Program Description: Purpose of the problem is to obtain the particular solution of the differential equation y″+9y=2sec3x by the method of variation of parameter.

Summary introduction: Problem will use a variation of the parameter method for the non-homogeneous equation y″+P(x)y′+Q(x)y=f(x) which has a complementary function yc(x)=c1y1(x)+c2y2(x) . The Wronskian of two independent solutions y1 and y2 of the associated homogeneous equation is W=W(y1,y2) and a particular solution of the non-homogeneous equation is yp(x)=−y1(x)∫ y 2( x)f( x)W( x)dx+y2(x)∫ y 1( x)f( x)W( x)dx .

What is the worst case time complexity of the following algorithm for i = 1 to x do for j = 2^((i-1)x) to 2^(in) do print(i,j)

Prove for each pair of expression f(n) and g(n) whether f(n) is big O, little o Ω,ω or Θ of g(n). For each case it is possible that more than one of these conditions is satisfied:1. f(n) =log(n2^n), g(n) = log(sqrt(n)2^(n^2))2. f(n) =nsqrt(n) +log(n^n), g(n) =n + sqrt(n)logn
