Hello. I would like to knwo how I can find 2 different tangent lines in the same curve and extrapolate it to find the intersection values.

Exactly like in this graph:

I have a similar graph and I need to find Tg using this method.

Thanks in advance.

Hi,

You can use the Tangent App to plot the two tangent lines.

Once you plot the tangent lines, you can find the intersection values by using the Intersect Gadget feature.

Thanks
