Sentence correction

AnonymousIs had used correctly?

Yes, but it's "lecture notes". No "s".

I thought I had sent you a copy of the lecture notes.

Thank you for the correction.

I am also confused about using the word remaining or remainder, in this sentence:

Please send me the remaining notes when you have a chance.

Or should it be 'the remainder notes'?

The word you need is 'remaining'.

Is the sentence written correctly with remaining?
I would also appreciate if you tell me what the sentence means with the word remaining?

Thank you.

I think that's been answered already. Yes.

You wrote a sentence whose meaning you don't even know? That's strange.

What remains is what is left.

Thank you very much. Actually a friend sent me this message. So the word remaining means the notes that are left that I still did not send him?

Thank you again
