Sorry for my confusion but (26:43) why have you got (H, t) as (x, y) when looking on your graph shouldn't it be (t, H), therefore m=5-2/3.23-1.43?

In the models discussed here at the end each time there have been clarifications that actually these results are not that reliable. How is this kind of modelling then useful? I realise future learning would hopefully give me a better insight into this aspect of modelling.

hi sir, for the questions where it asks to find an equation linking v with t for example, is it okay if you use simultaneous equations to solve it? instead of the gradient? cause I still get the same answer

[QuaternionPhysics]

In these modelling cases, is the dependent variable always on the y-axis?

hi sir, if the question said t is the number of years AFTER 2004, for example, does t at 2004 =0 and if it said t is the number of years FROM 2004 does that mean t at 2004 =1?
