I can see the sine one. We actually priced the cosine rule as c² = . I always do it this way trying to get the link the side you want use opposite angle.

It did prompt some interesting discussions.

I am confused what do you mean?

#Mathstoday we proved the cosine and sine rule. Y10 mic drop moment

#mathstoday#alevelmaths discussed with my y13, following an assessment, appropriate answers to the "Why might this assumption not be valid?" And "is this conclusion valid?" Answers like "the government aren't going to lie" "the flowers might be dead" are probably not going to get marks...

Yea I go through phases of podcasts

I tend towards audio books for this reason. 45 min commute means I get through about a book every 2 weeks. Just finished this, it's the 2nd in the series of Queen solves crimes ...

It already seems to have gone? There are others though...

This is so true. It's also so expensive considering you have to buy packs of 10, we have 31 entrants this year. If that 1 kid doesn't show up I'll be so annoyed. We've had so little time to prepare. KS5 leads have transition to sort, y13 UCAS stuff, a busy beginning of term in general as well.
