Substitute x and y into the equation of the tangent,

PB and PA mean the lengths from P to B and P to A respectively. You could do this with trigonometry, or a formula which I think is introduced in Core 1.
5. So i tried to find PA using the equation and I got 1+2p^4 and PB=1+2p^3 but I feel thats wrong
6. nvm im an idiot. I got it thx
