Equations of circles and tangents for OCR GCSE (9-1) Mathematics Higher tier (J560). 40 exam-style questions with fully worked, mark-scheme-annotated solutions: the equation of a circle centred at the ...
As the tangent is a straight line, the equation of the tangent will be of the form \(y = mx + c\). We can use perpendicular gradients to find the value of \(m\), then use the coordinates of P to find ...
