That was super helpful sir, thanks so much. Are you going to be doing further statistics 1 2022 any time soon.

Correct me if I'm wrong, but in 8:31, shouldn't it be a 1-(e^x^2) under the square root in the denominator as the argument for arcsinx is x=e^x. However, it wouldn't affect the answer as it dissapeares when you multiply it to the LHS, just a small observation

I'm so confused on question 7a, can't you just simplify cos(1+ tan) to cos+ sin ? That is much easier to differentiate and solve for

in question 4 ii), its much quicker to consider the triangle and use |z| = 5sin(pi/3)

For question 2 how do you know to use that matrix like where to put all the values?

[flashgq]

where can I find mark scheme for this paper?

For question 7 how do you know that integrating between pi/4 and 0 gives the triangle area including the white part and not just area R?
