See if the attached file helps.

You must write the imaginary unit as 1j (without a space inbetween) and not just as j and you mixed up 1 and l (lowercase Letter L) quite sometimes.

thank you very very much

please i need you help again with the graph this time .

You mixed up variable i with imaginary unit.

I also corrected the wrong index in omega.1. You used a vector index but it should have been a literal index. This had no negative effect to the calculations, though, but it created omega as a 2 x 1 vector.

BTW, there is no need for PM if you have a follow up question.

dear  @Werner_E 

i'am afraid i need your help again , i tried my best to fix it on my own but i didn't succeed

this is the last part and i hope i wont bother you again 

thank you in advance

You have to define the resistors R1, R2, R3 and capacity C1.

yes but i don't think there value needed  @Werner_E 

 

[Werner_E]

The error in your sheet is because those values are not defined, so you will have to define them by using := before you use them.

@Werner_E  i did it but still there is a 3 error need to fix

[Werner_E]

You defined S1 for index 0 to 30 but now you try to access vector values with indices 31 to 100 which do not exist.

So either use k:=0..100 in all places or k:=0..30 everywhere.

thank you so much i fix it
