Great question. I’m a little picky about readability for students so would prefer “sketch the graph of y against x ‘given’ … ‘for’ values of t ….”

We don’t use a Casio at my school but the TI we use has a normal pdf command. It can be used to find the function value at a point when sketching a graph of the prob function. Not sure how often that would be necessary.

This is in Australia and when X is defined at the set up of the questio, before all ‘parts a, b’, then they cannot use that to represent any other random variable. Same if a function f(x) is defined then they must use another function name for transformed functions etc.

We would certainly penalise. X is defined with its parameters and part b is an entirely different distribution.

Our exams tend to be the same. Efficiency is part of the key to success in them but that comes at the cost of time to think.

Yep that would result in the worst sort of formula plugging without understanding.

I don’t know what ‘that formula’ is. Is it very confusing?

We use this, as a point of inflection is described as where there is a change in concavity or curvature from up to down or vice versa. I generally focus more on tangent position of above or below the curve.

Happy Anniversary. We also got married 28 years ago on the 22nd. A month after bushfires raged in Victoria. The earth around us was scorched but I remember the day being fun and full of love.

I gave a little (possibly embellished 😆) bio of Gauss today whilst teaching sequences and series. Makes the students roll their eyes but they laugh as well.

I used to over think it and lose sleep but as I have gained more experience I deal with it better. Try to identify where it went wrong - me, the students or other factors and how I can do it better in the next lesson.

Sorry - never going back there. I cannot in anyway support an organisation headed by someone so revolting.

Does this not rely upon the fact that the gradient of the circle is -x/y, either from implicit or parametric differentiation? If so I see it as formula plugging not understanding.

And relatively speaking, Euler is pretty modern!

I live in #Goldstein and think Zoe Daniel is an excellent MP, but Labor were never a chance in this electorate. It was always Liberal v Independent

It is Australian but the Australian Mathematical Sciences Institute (AMSI) careers.amsi.org.au has some wonderful posters and other materials about careers that require maths that I think are universal.

I have not done it this way before, always started from y=ax^2+bx+c and completed the square. Nice to do it differently.

In Aus mixed attainment is the default. I had not heard of ‘top set’ etc until my daughter worked in England this year. Has this always been the arrangement?
