@ecterrab @Mariusz Iwaniuk I'm sorry to bother you again but I'm totally new at this program, I have the Maple 17 in my PC, does here the physics update work fine or not? Because I can't find out what version it's.

Second of all I have a math questions,is lambda n like a sequence or a series? because I actually dont understand the math behind the equation and how to actually solve it for a value for t,k,d,cp, do you have anything that could help me out in this?

thank you so much
