Just realised I lost 3 marks. Screwed up the third part of question 2. :mad:

What was the answer? And what did you put?

so did I shah. you only had one solution right? so did i but then i remembered at the very end that id done it wrong and that 0 and 180 were also solutions so i just jotted them down with a limited method (i basically just said i did this wrong and there are two other solutions and showed they both equalled zero). a haha do you think i will lose 1, 2 or 3 marks out of 4?

It was to do with tan and cos and I multiplied through by cos to get sin and sincos and then factored out the sin. There was a 4 and a 7 there somewhere but I made an absolutely idiotic mistake that immediately docks me 3 marks.

If my answer was right then you probably got all the marks for that as well!

yes. 0, 124.5 and 180. if you didnt factorise you'd only get 124.5 (which is what i did). i put the three answers down but only the method for 124.5 ahha.
