[10pts] Let's imagine that we have a first-order differential equation that is hard or impossible to solve. The general form is: df g(e) f(t)-he) dt where g(t) and h(t) are understood to be known. It turns out that any first order differential equation is relatively easy to solve using computational techniques. Specifically, starting from the definition of the derivative... df f(t+dt)-S(t) (dt small) dt dt we can rearrange the equation to become... www f(t+dt)-f(t)+dt-df (dt small) dt In other words,...

1. Use Matlab to solve the differential equation (d^2φ/dt)=-(g/R)sin(φ), for the case that the board is released from φ0 = 20 degrees, using the values R = 5 m and g = 9.8 m/s^2 . Make a plot of φ against time for two or three periods. To do this, you'll need two .m files: one with your main code, which calls ode45, and one with the differential equation you're solving. 2. On the same picture, plot the approximate solution...
