Trigonometry

With the trigonometry question I forgot to do cos-1 I put cos without the -1 and got 7. Something.
Would I still get any marks, I worked it out as cos = adjacent divide hypotenuse. Would I get any marks?

Yes I think at most you would lose 2 marks

It was 2 marks, so I’m guessing I got 0?

oh i assumed you were talking about a big shape question. You might get 1 mark but don't stress about it everyone makes a few silly mistakes in maths
