Title: The picky stuff of specialist maths?
Post by: dekoyl on December 08, 2008, 10:59:20 am: Having done methods, I've been drilled with all the picky stuff that's required by my teacher and I was wondering if its required in specialist. For example:
*Finding the stationary point: "At stationary point, $\frac{dy}{dx} = 0$ "
*Similarly with x/y intercepts: "At x-intercept, y = 0 = $f(x)$ "
"At y-intercept, x = 0: y = $f(0)$ "
*Labeling all x and y intercepts with their coordinates on the curve
*Labeling minimum/maximum coordinates

I'm sure there's a few more but I can't remember ::)

Everything else seems right. :D

For example, you should never swap $x$ and $y$ around for no reason, without writing "Finding the inverse" or something that describes what you're doing.
