thank you mr mclogan you're my only hope for passing my precal final🙌🙌 UPDATE: I got a 50 on my test but that was just barely enough to pass the class!! again thank you so much now I can go straight to calculus instead of retaking it.. don't try to cram 2020 is all about those healthy study habits🔥🔥🔥
I believe it is because the domain of a tangent function is (-pi/2, pi/2), so your answer would have to be within the first and fourth quadrant. You can also think of it as being within 90 degrees in either direction of 0.
Because it's not a one to one function outside of that interval. One to one functions have inverses so restricting the domain from pi/2 to -pi/2 makes it an inverse function
You are teaching incorrect vocab! at 2:24, you says sec is 'inverse' of? Correct word is sec is 'Reciprocal' of cos!! INVERSE is NOT same as RECIPROCAL!!

Amazing as always. This video was very helpful, thank you sir.
Also when you dropped the cap of the marker at 3:08 it made me laugh haha.
you are very welcome! haha not the first time
thanks for making the video it was very helpful
Great explanation!
helped me so much
This man is getting me through highschool
Thank you
Why you take cos(theta)
Let's get it let's go 🚀🥳♥️💫
Why does tan only have positive domain?
Thanks!
