  1. I was able to push my way through that last probability question. For the first part, all it was was setting the sum equal to one, and then solving for cos θ. Then they asked for tan θ which is just (sin θ) / (cos θ) and since you're already given cos θ, just solve for sin θ using sin2 θ + cos2 θ = 1. The harder part was the last one where you had to integrate it. The problem I got stuck on on Paper 1 was number 9, when they asked you to find the values of k.
  2. I'm from TZ1 and I actually thought Paper 2 was harder than Paper 1! But Paper 1 was still pretty hard especially question nine, which I found quite tricky. On Paper 2, I messed up on number 7 ("Find when the total distances are equal") and I blanked on number 10 ("Find when the distance between h(x) and y = x is maximum). Did anyone get 23:00 for the high tide question in number 8?
  3. That's a good start. Now you just need to simplify the complex fraction:
