The tangent point is at (0, 5). The gradient is found using . Evaluating this for the two points, which equals -2. The gradient between the centre and the point given is -2. Step 2. Calculate the negative reciprocal of this gradient to find ‘m’ The gradient of the tangent to a circle is perpendicular to the gradient from the centre to the ...

Sep 25, 2024 · Take the first derivative of the function to get f'(x), the equation for the tangent's slope. Solve for f'(x) = 0 to find possible extreme points. Take the second derivative to get f''(x), the equation that tells you how quickly the tangent's slope is changing. For each possible extreme point, plug the x-coordinate a into f''(x).
