Exam 3 Review Questions 2.5 1. 2. 3. 4. 2.6 5. 6. 4.1 7. Graph the function y = 4 2x Find the inverse function to y = 4 2x Graph your solution to b and check that the two graphs are reflections across y = x Is the function
function [y_numeric,y_exact] = sample_rk4(tspan,y0,h)
% This sample finds numerical and exact solutions to the initial value problem
% y' = f(t,y)
% y(0) = y0
% The function f(t,y) is defined in the file yprime.m
% For this example f(t,y) = (2t + 1)/(2y)
