- To find the gradient use the fact that the tangent is perpendicular to the radius from the point it meets the circle. Work out the gradient of the radius (CP) at the point the tangent meets the circle. Then use the equation ({m_ {CP}} times {m_ {tgt}} = - 1) to find the gradient of the tangent.

Sep 4, 2014 · The gradient of a function is also known as the slope, and the slope (of a tangent) at a given point on a function is also known as the derivative. To find the gradient, take the derivative of the function with respect to #x# , then substitute the x-coordinate of the point of interest in for the #x# values in the derivative.
Find the gradient from the centre of the circle to the tangent point. Calculate the negative reciprocal of this gradient to find ‘m’. Substitute the x and y coordinate values along with ‘m’ into ‘y=mx+c’ and solve for c.
