Sorry, In 18:45 why did you use (0 with a slash in the middle)with the tan , and said it's undefined with sec ? Is it the same thing or something is different? I would be happy to hear the answer, thank you
We use tan theta at points for the tangents of different angles where the angle is undefined due to asymptotes. An asymptote is a line that graph approaches but never reaches. For the point tangent to the unit circle, this occurs at 90 degrees and again every 180 degrees, so the next asymptote after 90 degrees would be 270 degrees, and so on. The same would also occur in the opposite direction, so after 90 degrees would be -90 degrees and so on.
you're saving me rn🤞
Yay!
I wish philippines has a teacher like u
I like the "Co - pilot " trick to remember Cosine- secant
Amazing how you conveying the lesson, thanks Yay
I'm a machinist. You have no idea how I use this. Your videos have been very helpful for me :)
I'm honored, Derek.
I loved the "pilot - copilot" memorization tip!
i would love to attend a class like this
such a good teacher
Wow!
"Thank you!" (Obama voice). Thank you, Ebrima, for seeing how special the ObaMATH series is.

Thank you
How did you get horizontal?
Good
He lowkey looked waaaay better with longer hair
nah
I'm grateful
A squared is 4 squared plus -1 squared which it +1. 16+1 is 17. I don't know where the 15 came from. Loved the vid tho
they were trying to find a squared not c squared in this case
How is that root 3 comess from no where..
