I missed class last Thursday and I am completely confused about the homework. I tried reading the text but there aren't any example problems like this one. Anyone know any free resources for James Stewart Single Variable Calculus?
Well here is the question:
For what values of k does the function y=cos kt satisfy the differential equation 4y"=-25y.
For those values of k, verify that every member of the family of functions y=A sin kt + B cos Kt.
I tried solving for y" and setting the equations equal to each other. To tell the truth I don't understand what the question is saying.
Thanks for any help!
