This channel help me alot since i was in my grade 11, now im in 3rd year college engineering thank you for your hard work

[davidhicks]

beating my head against a wall for 5 hours trying to understand what my professor is saying. Halfway through your video and it all makes sense. You are a blessing.

[donaldtuten]

Honestly, teachers should be taking notes from you on how to teach via online.

[crneymar]

Tell me why this dude is better at teaching than teachers who went to school to be teachers. AND his content is free

[jennahalcomb]

This channel is the reason I got accepted into college I swear😂 literally I don’t know why I understand it all 1000% more when it’s explained this way than when my teachers would explain it.

I’ve been using this channel as a resource for year in high school and now in my first year of engineer in college I’m still finding his videos so valuable. Thank you so much for creating easy to understand content. We all appreciate it very much

[patrickaustin]

it cannot be said enough how much of a blessing this channel is. I am taking an online pre calculus class and it is unbearable to try and teach myself everything from the textbook. Rather than show the work, the textbook takes lots of time to explain derivations. It is so annoying. I work full time, am taking another class (biochemistry), shadowing at a hospital, applying to PA school, and next week is finals week. YOU ARE SAVING MY LIFE LOLOL THANK YOU

[patrickconnolly]

I know you get a lot of comments like this but truly thank you for this content. My teacher expects us to understand all of this within a 1 hour class time, and thanks to you, I can figure out what to actually do. Thank you so much.

*Domain of inverse trig functions*
arcsin [-1, 1]
arccos [-1, 1]
arctan (-∞, ∞)

arccsc (-∞, -1] and [1, ∞)
arcsec (-∞, -1] and [1, ∞)
arccot (-∞, ∞)

*Range of inverse trig functions*
arcsin [-π/2, π/2]
arccos [0, π]
arctan (-π/2, π/2)

arccsc [-π/2, π/2]
arcsec [0, π]
arccot (0, π)

My teacher explains so fast that it ends up leaving me stumped by the end of her lessons, this video allowed me to take my time and pause to understand what was going on (and now I fully understand!) Thank you so much!

[jadencleveland]

I've been struggling in my math and chemistry class for college, and your videos help me so much! Thank you so much for posting them!

[teassister]

“we know that __ is equal to __” no i do not know that 😭

[Tmzski]

You should note that tan^-1 does not include the pi/2 or -pi/2 for the range, since you would technically be dividing by a zero which is undefined. Therefore, your range for inverse tan is (pi/2, -pi/2), not [pi/2, -pi2].

[laurenorourke]

thank you for saving my pre calculus grade!! your videos have really helped me!!

[reemavishwanath]

I can’t tell you how much you help with understanding precalc. Don’t ever stop running highschool math.

[pavelgutierrez]

It's like you're reading my mind. I was taught this in class THE DAY THIS CAME OUT, didn't understand it. Now I'm doing homework, and this has come in handy. Thanks, man

[llortaton]

IDK why, but I love it when he goes "if you get this answer, *slight pause*, you WILL get it wrong."

[mildew]

omg i have a test tomorrow and I was sure i was going to fail until I watched this video! thank you so much, i never thought i would be able to understand the concepts until now

[qflexmoves]

Broo, you’re really out here doing the Lord’s work! Like God bless you for real. 😢 I was sitting in the library feeling all kinds of frustrated and ONCE AGAIN the OG Chem Tutor saves the day.

I bet you real life just sitting behind the desk with a cape on. Doing it real big. Your new name is Tutor Teresa. Feeding the intellectually hungry and serving the mentally poor.

Thank you brother.

[cameronleslie]

My teacher can't teach for the life of her so you've been my teacher for the past month. Thanks.
