If you are wanting to prompt a imput then it would be:
? prompts the user to imput a value and that value will be stored into A for later calculations.
If that is not what you are wanting and are wanting to replace sin(2*pi*n) then I think you would want to do an if function:
Sorry again if thats not what you wanted, I don't think there is an exact function that will replace it but you can use the If statements.
thank u again
I found an ugly way to do that ))
for relapsing just cos(k.n.π)=1 jast for k=2 to 6 step 2
for 2⇒i to 6 step 2
if s1=0 :then
but its not a good cod :| I had to do this ring for sin() and I had to do it like 6 times in a program to get all I want!(for 3 variables like "an")
I hope someone has a better idea!
