Thanks to Phillip Sakellaridis of St Francis Xavier College for pointing out an error in MC Q15 in the original version.
Thanks to Isura Wanniarachchige for pointing out a mistake in Q5e ii.
In part i, m is defined as a positive real number. When you solve for u and v you get two solutions for u and v. If you sub u= half times (root(5) – 1) into derivative g (u) you get a negative answer meaning m is negative. This solution should be rejected as m is greater than 0.
