Math246 Lecture 6: Second Order Differential Equations a y +b y cy=h(t) Now, we will be looking at second order differential equations of the form . Of particular interest is when h(t)=0. Let’s look at some examples. General Problems y +25y=0 1. What function essentially doesn’t change when you take its derivative Yes, the x exponential function e . So now all we need to do is get the exponent correctly. One e5t 25e 3t solution is . If you take the derivative twice, you en
