Tangent Lines (using Desmos slider)

This is brief tutorial on Tangent Lines of a function using the Desmos graphing calculator.

This just made a math assignment of mine a whole lot easier. You are a legend.

Awesome demo, thanks for sharing the link!

[ckellough]

can this (creating a slope-tangent slider point) be done for a non-function? Say, something implicitly defined like a circle or an ellipse?

[leifbohne]

Thank you so much for this. it worked well and is really handy.

How would u find the tangent line of the graph if there are three variables e.g ax^3+bx^2+cx+3

[sagecoyote]

How do I add the approximately equals sign in the [g(a)]=m line?

Quite late to the party, but hopefully you're still seeing these comments: Is it possible to see the tangent line as an equation? I can't get desmos to show the line written as a function.

how do i add the functions to find the gradient of the tangent. im struggling

[stephen]

awesome for checking work <3 ty so much

[komrade_koala]

But how do you make this? I know theres a link in the description but whenever i try to make one myself, I type in the exact stuff and it doesnt work
Edit: Nevermind I figured it out, thanks for the video!

Literally did not give any information about HOW to make this happen. Useless.
