1. ### Does my overall subject result take into account passing the exam hurdle as well?

For one of my subjects which had an exam hurdle of 50% i got 68% overall but don't know what i got in the exam, and don't know my assignment grades either. If I got over 50% overall but failed the exam hurdle would my grade show up differently?

solve 2pi cos(((2pi x - 2pi))/(3) = 0 for 0<x<3 i'd first have to multiply the domain values by the coefficient of x, which is 2pi/3, and would I then need to subtract 2pi/3 form the domain values? Thanks

This question is for vce maths methods. The second derivative isn't part of the maths methods course. Would a gradient sign test work in this instance to find the value of x for maximum and the value of x for minimum?

if we had to find the derivative of sqrt(x^2+3), and evaluate it when x = 1, we get 1/(sqrt(4)), which so in this case, would it be 1/2 and 1/-2? or just 1/2?
