How to Find the Tangent on a Graph in Excel. The tangent is defined as the single point where a straight line meets a curved surface.

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 ...

2. Consider a tangent of the curve \ (y=17-2x^2\) that goes through the point \ ( (3,1)\text {.}\) Provide a diagram of this situation. Can you draw two tangent lines? Find the slopes of those tangent ...

Find the slope of the tangent line to the polar curve \ (r=2\) at the points where it intersects the polar curve \ (r=4\cos \theta\text {.}\) (Hint: After you find the intersection points, convert one ...

The tangent is perpendicular to the radius which joins the centre of the circle to the point P. As the tangent is a straight line, the equation of the tangent will be of the form y = m x + c.
