In many of the following problems, it will be essential to have a calculator or computer available. You may use a software package† or write a program for solving initial value problems using the improved Euler’s method algorithms on pages 127 and 128. (Remember, all trigonometric calculations are done in radians.) Use the improved Euler’s method subroutine with step size h = 0.2 to approximate the solution to the initial value problem at the points x = 1.2, 1.4, 1.6, and 1.8. (Thus, input N = 4) Compare these approximations with those obtained using Euler’s method (see Exercises 1.4, 6).

Social Work Research Dr. Choi Week 1 Monday, August 22, 2016 Introduction to the Class ● “Social work values & missions continue in social work research.” Something to remember throughout this course. ○ As we’re competing against similar fields, research helps empirically validate social work as a profession.

You salaries might be funded through those
