For U , this is t years after 1990, and for V it is t years after 2000, you need to alter it, other than that I have got as far as you.

If tan(x)=1/0 ie infinity, does x equal 90, 270 etc...

(I ask this as I have seen it before on an exam paper but would like further confirmation?)

I really should have read it more carefully in the first place. Had some filthy equation before I realised what the value of A and B were haha.

This is as far as I am. Have two equations in terms of p and 'altered' t which I can set equal to each other.

sorry for the scrumpled back of a c4 paper haha
Wouldnt you put t as 10 in the U equation and not t+10? or would it be t-10

confused.

You can work out p, read the first two lines.

put t+10 into U to match the starting year with V of 2000. then equate

as somebody else has said when the denominator=0 there is an asymptote. So create an equation and solve for x. This value of x = beta. I've posted my solution if it helps, also is there a mark scheme for this?

Teeeeeeeeeeeem I don't understand b of this question, how does it equal zero for a vertical asymptote 😭😭Attachment 425503
