Can't you just use the double angle formula for the 2nd question? Isn't it easier that way and shorter

[@tahmidahmed6524]

Isn't the domain for a restriction on the x-axis 2:21 so isn't it meant to be for -pi/2 < x > pi/2.....slightly confused

[@rhett-says-hullo4229]

I don't get it either

[@titchyASSASSIN]

​@@rhett-says-hullo4229 the restriction is for t and t is used to find the x values

[@rhett-says-hullo4229]

@@titchyASSASSIN thanks! I understand

[@UnbeatenPlayzMinecraftandmore]

Which year 1 video are you referring to sir?

[@yakiyakiyaya1117]

in the exam will we have time to actually to draw out each parametric equation, it takes me ages to draw one

[@peterhunt1968]

Could you tell where your accent is from? Great lesson by the way, very useful, thanks 🙏
