Oh no! Just realised I made a stupid mistake solving
x=sinθ=43±17
I think I added 180 instead of 360, therefore got 164 degrees and 16 degrees. I can't really remember. How many marks would I lose? I did state that x=sinθ=43−sqrt17
When you form your own vector eqn of a line, I used alpha instead of meu, is that fine?
yeah, you could probably use a little picture of a cat as a parameter if you wanted and it wouldn't change the maths. greek letters are always good though.
