IB Math AA HL May 2021 TZ2 Paper 1: I hate everything

[gbzhou]

For Q12-a, horizontal translation left by 1 unit, and then then horizontal stretch by 1/2, would make it arctan(2x+2), not artan(2x+1).

Correct approach should be horizontal translation left by 0.5 unit followed by horizontal stretch by 1/2

Without you, it would be very difficult to understand what is going on in the paper. Thank youuuu

20:53 btw it's supposed to be 9, not 25, and the answer is the square root of 18 ^^ thank you sm for the video though!

15:00 can't you just leave it as "l1 and l2 are either parallel or incident"? Because in neither of those cases will they intersect -why is it mandatory to state specifically that they are parallel?
