Hi Professor, I have been asigned to develop some educational applets to simulate LRC circuit and to perform some calculations to enable student understand some physics principles. So i looked at your wonderful work and i would like to find out if you could send me some code to learn from it in order to acomplish my task on schedule. I promise not to copy but use it as a guide to develop something complex than yours. Thank you very much. Have a nice day. Barffour.
