"Y incredible thank you hope you got all the right gifts! C"

"Could you please include the commands for the maple plots. Also, what can you say about V-dot when alpha = 0? I think its the same case as alpha > 0."

"Thank you so much I have realized that my memory is part of the reason why I get stuck in certain parts In other words the simplest of things from long term memory I forget while the difficult parts I can think through which means that I have to go back and revise basic simple algebraic manipulations Thank you so much for your meticulous clear and exact answers"

"Hi thanks very much Can you please explain to me point 1.13 where did you get that from Is that in this case from Csin(ωt) differentiated twice"

"Thank you."
