Visualizing Trigonometry: Tangent Function

This video is inspired from 3Blue1Brown's Lockdown Math series.

This is the best explanation of this topic that I have ever seen. No words, just a perfect visual representation.

love how you animated this explanation!

Good work, , waiting for upcoming videos

Essentially:
Tan (theta) = Sin (theta) / Cos (theta), i.e Opposite/Adjacent
When (theta) is 90, the opposite and adjacent sides cease to exist, i.e opposite = 0 and adjacent = 0.
Division by 0 is undefined and therefore the tangent graph approaches 90, but never gets there, because it's undefined.

Edit: I made a mistake.
The opposite side does NOT cease to exist. It becomes the same as the hypotenuse because the adjacent side disappears.
