I am revising with past papers for the 2009 Standard Grade Credit Maths. Would appreciate some help with the following past paper example.
Solve algebraically the equation
5 cos xo + 4=0, 0 ≤ x ≤ 360
If anyone knows where I would be able to obtain Standard Grade Credit past paper exemplar answers (that show working not just the end result) would much appreciate if you could let me know
I have only got around 2 months left to exam time and need all the help I can get
Thanks in anticipation

Hope that's of some use to you. Good luck with your Maths! (and the rest of your Standard Grades - hope you do Higher Maths by the way, it's rather fun )
