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 ...

The tangent As a tangent is a straight line it is described by an equation in the form y b = m (x a). You need both a point and the gradient to find its equation.

To find the tangent line to a curve at a point P we first pick another point on the curve a little bit away from P. Call this point Q.

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 ...
