Let 2x=Ø, then divide both sides by 6, and you get it in the form of the first proven identity. Then you should have sin^2(x)=1/3 OR sin^2(Ø/2)=1/3

I think uni is something that you can only really experience once, the lifestyle is meant to be fantastic, pretty much ruled apprenticeships out completely on that basis

Hmmmmmmm i think I might end up doing like only a year of apprenticeship and drop out and reapply to uni like a gap year tho that once again is uncertain 🤔 it’s mainly coz I’m not sure whether I actually want to do that course too
