Edexcel C3 Q8 ecf marks HELP!!

For question 8, I used the form Rsin instead of Rcos and thus getting the wrong angle for alpha in the first place, will i get ecf marks throughout parts b and c if my methods are the same as urs? my friend told me if my methods are correct ill lose the Accuracy marks but will get all the method marks? how many marks do you think that will be?

As far as I was aware, ecf only applies to further parts of a question. E.g. if you made a mistake in part a) They would let you use that mistake for parts b) and c) for full marks.

To be honest with you I don't think you will get a lot of marks for that. - Maybe even nothing at all. Even if I'm wrong, it's best to assume I am correct as I know that I for one would rather be under the impression I did badly and be pleasantly surprised as opposed to trying to calculate the highest possible grade and then being shocked on results day...
