The highest exam mark will go to the person ranked first, while the lowest exam mark will be given to the person who is ranked last within your class. Everyone in between has there marks adjusted to fit within the range.
y = ln[1/cos(x)^1/2]
= ln [cos(x)^-1/2]
= -1/2 . ln[cos(x)]
= -1/2 . -sin(x)/cos(x)
= sin(x)/2[cos(x)]
I think thats the correct answer, i dunno could be wrong
Re: 回复: Re: ~~Mathematics Revising Game~~
Integral of sec^2(x) = tan(x)
Area = tan(pi/4) - tan(0)
= 1 - 0
=1 square units
For the function y=x^3 - 3x^2 - 9x +1
i. Find the coordinates of any stationary points and determine their nature
ii. Find any points of inflexion
its to hard to say, best chance is just to go by the text book because atleast you will have a background of what was the policies in place. you could also do a search through google, union websites and australian govt. website to see what changes are going to occur
