So, the gradient at any point on the curve is the y value at the point π/2 further on. It emphasises that sin x and cos x are really the same function that differentiates to itself with a phase change, not two different functions differentiating to each other (with a minus sign floating around)

We're developing this programme based on work we've already trialled in this area: amsp.org.uk/maths-into-ai/
If you DM me I'll send you my email address and we can chat further...

Are you counting the COVID years as having Maths exams?

I have a strong preference for doing it through the distributions menu so that I always see a picture of the distribution curve.

You can also do a normal Normal Distribution calculation then edit the probability and it will reverse engineer it for you.

Home - Calculate - Catalog - Distribution (9) - Inverse Normal (7)
Syntax: InvNormCD(tail,p,mu,sigma)
tail, mu and sigma are optional
tail is -1 for left and 1 for right
So InvNormCD(0.05) = -1.644
Or you can type InvNormCD(-1,0.05,0,1) = -1.644

I've never found a way, but I know that if I set it to blue and then go back to cursor then when I go back to pen it's still blue. I usually do this when I start the slideshow.
Red is an odd choice for the default!

Ctrl-P: Pen
Ctrl-L: Laser pointer
Ctrl-A: Arrow (i.e. cursor)

Yep - pretty much most people can use it. Save to pdf is really quick too and creates a version that people can open on almost any device.
As with most Microsoft stuff it's easy to use and universal, though somewhat lacking in advanced functionality (or style!).

It's a really versatile tool for putting a question on the screen with space to write on too.
I use it frequently but I (almost) never use animations.

In general I'm a fan of a menu-driven approach. I didn't need to look up where the nCr button was just now - it was on the first guess of the menu where I expected it to be.
