Hi Mr M,
For question 4, I used the right trig identities and got to 4sin^2x - 7sinx + 3 = 0 (not sure if I've remembered it correctly) but then I must've stupidly factorised it wrong and ended up with x= 30, 150.
Do you think I'd get any of the 6 marks, seeing as my method was correct(ish)?
Thankyou!
