TMUA Paper 2: Shapes

[@tymoteusznh]

Hey boss, I've watched some videos. I've been scoring well in practice runs, but many Paper 2 videos (and modulus) have helped me streamline my thinking immensely and upped my confidence. Great videos, hoping for a good grade now, thanks so much.

For the last question, I applied the cosine theorem by substituting x as the lenght of PQ and get a quadratic. Then I said to myself '' If this quadratic has only one solution (meaning that the discriminant is equal to 0) then the value of p will uniquely determine PQ. And I got 4p^2-4=0 and thus p=1.

6:34 I’m a bit confused, because for necessary statements isn’t it “if A then B”? Then here why for necessarily true is it “If B (perpendicular) then A (statements)” ?

[@rtwodrew2]

To test whether something is necessary, find a time where the result happens (perp diagonals) without the claimed condition. If you can, the conditions are not necessary

[@kausarlolz]

@@rtwodrew2 ahh i see thank you. Then what about just “must be true” statements

[@rtwodrew2]

Which must be true is the same as which are necessary

[@kausarlolz]

@@rtwodrew2 oo thank you so much !!

Would we need to know the formulas for the volume of a pyramid/sphere/cone?

Hey could you do integration?? And the area when u change the function ? I know the exam is on Tuesday but I find it difficult 😅😊

[@ellio_1367]

What time is the exam on Tuesday? I can't find it anywhere on the website. Does it depend on my Sixth Form?

Mine's at 9:00, I'm assuming it's the same for everyone else?
