You're pretty much there aren't you? You've worked out the gradient of the line OU; you've worked out the gradient of the tangent at P (you don't need the full equation of this tangent, just the gradient). Now set them equal to see when they are parallel.

it is the full question what are you smoking. the diagram for the question was at the end of one page and the questions related to it where at the start of the next page thats why theres two diff attachments for the whole question. and even if the whole question isnt there u dont need anything from the previous questions.

thanks
