LOGCETERA:
How many marks do you guys think VCAA will detract if you wrote sin(theta) as sin^-1(theta) all throughout Q9?
VCEStudent2034:
And if you let that equal zero, you get Pi/2. Plug into sin(theta), you get 1.
Writing Overload:
Did anyone get q is between 0 and 1 not including 1 for the second part of that question?

But note that the domain of g is restricted, I believe to \( (0, \frac{ \pi }{3} ] \).
