Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

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.

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.

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 an expression for \ (m\) and \ (b\) (as functions of \ (x_1\)) such that the equation of the line \ (y=mx+b\) is tangent to the curve \ (y=f (x)\) at \ ( (x_1,f (x_1))\text {.}\) ...

How to Find the Slope of a Line on an Excel Graph. In math and statistics, you may occasionally need to calculate the slope of a line generated by coordinates in the (x,y) format.
