Ahhhhh what was that projectile

 

[4u Boy]

I was studying binomials my whole life

 

[Arrowshaft]

What do you mean traps? I thought the paper was fairly straightforward

Did u get the last q out

 

[AHafza]

Was the projectile 30 degrees
And the last part of q14 2sin(alpha/2) ?

Yep

 

[Arrowshaft]

Why was the last part 3 marks though lol?

 

[Arrowshaft]

What did you get for the inverse function q (10MC)

 

[AHafza]

Was the bionomial k= 5

 

[AHafza]

What did you get for the inverse function q (10MC)

4

 

[Chamoun]

Anyone have the paper ?

 

[Arrowshaft]

Wait what. I got 15 for binomials ... must’ve messed up something! Faaaaaa

 

[programen]

assumed part 2 to do part 3 since I didn't get part 2 of the last q

is 0,0 on the inverse

 

[Arrowshaft]

What do you reckon will be the cut off for a 98?

 

[AHafza]

15 is correct

 

[Arrowshaft]

15 is correct

Oh, you said 5 before...

 

[AHafza]

15 is correct

Bionomial are symmetrical, 5 and 15 are the same

 

[Arrowshaft]

How’d you explain last part of 14 (b)?

 

[AHafza]

How’d you explain last part of 14 (b)?

Complementary angles

 

[Arrowshaft]

Bionomial are symmetrical, 5 and 15 are the same

Binomial coefficients are symmetrical...
