    The tangent at that point would be perpendicular to the line joining the point and the centre of the circle. Find the gradient of the line joining the centre and the point and then you can work out the gradient of the tangent as they are perpendicular

    let  y = \frac{1}{2} x into the circle's equation. If it is a tangent, the discriminant would be 0, meaning that it has equal roots, hence only 1 real solution, and in order for a line to have only 1 solution with a circle, it would have to be a tangent.

    Then use that information and carry on working out the actual real solutions, which should give u x and y coordinate of the one they gave you.

    You need to know how to integrate x^3sin^2(x)sec^3x(e^2) at GCSE

    Never been taught this. Would it be further maths GCSE?

    I'm joking, that's second year A Level maths, maybe a bit beyond.
