hi, Just wanted to say that your videos are absolutely lifesaving. i was absent for 3 days in my precalculus class and knew 0% what was going on, and this video absolutely saved my grade.
doing uni maths for engineering where this is assumed knowledge which i mustve missed long ago. It has been a really challenging couple weeks and ive been so stuck, until this, because i didnt even know what i had to study to meet the prerequisites. you have saved my education, my friend. Please keep up the awesome work!
this video saved me. My online trig professor likes to put notes online and audio to explain the notes and it just was too confusing. I needed to actually see it being done. Your explanation was so easy to understand and it helped that you went through problems one by one. By the second problem I was answering before you were done explaining. THANK YOU SO MUCH
Thanks Mr. Mario for sharing a detailed lecture on inverse trigonometric functions. Very important to understand these fundamentals to solve problems in Mathematics and Physics! Happy Teaching ✌️
Thank you for your concise and well explained videos. I've been out of academics for 9 years or so and I'm going back to college and your videos have been amazing refreshers and reviews to get me caught back up to where I was.
I'm from the french speaking part of Belgium, cannot find clear videos about this subject in French on youtube. Really glad that I discovered your channel ! You have a great sense of pedagogic approach. Thank you very much
Hello, I have a question here regarding your Unit Circle and I am sorry just incase this was already addressed in the video I might not have been exactly paying attention but,,, My question is: why are your values in the fourth quadrant of the unit circle different than the normal ones I have seen? Like for pi/6,, the one I know is 11pi/6
For arcsin and arctan when I Looking for the angle should I get it from pi/2 and -pi/2 or is only the positive pi/2 is included? I mean when the question wants the value from (0,1) and (0,-1)
Thank you so much for this video!! You truly are a life saver! I have one question that I am struggling with... I don't understand why arctan(tan π) and arcsin(sin 3π ) = 0 and not π. Greetings all the way from Holland!!❤️
Greetings Amira! It’s because the arcsin and the arctan have a restricted domain from -pi/2 to pi/2 meaning the answer needs to be in that interval....otherwise if we didn’t restrict the domain there would be an infinite number of answers. Hope that helps!
Why is it, in Quadrant IV, that the variables of pi are not (11pi/6), (7pi/4), (5pi/3), and (3pi/2)? On all of the Unit Circles that we have constructed for my class, those values are the variables listed in Quadrant IV...perhaps a detail my teacher missed - are they supposed to be negative and without numerator variables (excluding pi) instead?
Pearlie, It has to do with the restricted domain. You may want to watch the video again where I discuss the restricted domain for sine cosine and tangent.
That's less than half of what you'd pay for a college course if that puts it into perspective. And having a math teacher that actually gets you to understand the subject matter is rare!
@@ambientscience2951 thank you so much! I'll definitely consider it! I have a subscription to Great Courses Plus that I use (tons of awesome courses). Between Great Courses and Mario's Math videos I have a c in trig and precalc instead of an F, hahaha
Are the private videos in the algrabra 2 needed for my learning experience. And do you think it's possible to teach my self it in 2 1/2 to 3 months for a placement exam?
Some of the videos I have not released yet. If you are looking for a step by step with lots of examples and more in depth teaching I recommend my Algebra 2 video course I have for sale.
on behalf of all calc students studying for their trig tests the night before…..YOU ARE A LIFESAVER

You’re welcome Harjeet!
Damn Johnny, i didn't know you were such a good math tutor... Such diverse talents 😉👍
you made it so easy, thank you. I needed the refresher and caught on immediately
I am from India and all my friends in my school and in my coaching institute are fab of yours and your teaching...🙄🙄🙄
Inverse Trig Functions FINALLY make sense!! Thank you Mr. Mario!! Love you
You’re welcome Paul!
Thank you! Laying the unit circle and the problems in the same board made me understand it quickly.
Thanks so much, this video definitely helped with my summer precalc class (the website didn't even teach anything)
I swear I know this guy from somewhere. He looks so familiar
I need to check your browser history..
You need to be grounded
That's because he looks italian. There's lots of Italian in America.
@@mrfilmmaker3237 lmao
Im dead💀💀.
Omg so helpful thank you so much
Just took algebra 2 and I was really curious about this, I’m so excited for precalc next year
THIS VIDEO SHOULD HAVE 1 MILLION VIEWS. THANKS MR. MARIO YOU REALLY HELPED ME!!
Thank your sir! You are an amazing teacher! Thank you for explaining everything in great detail.
This actually helped and I’m so happy 🥳
What an amazing explanation! Thank you so much.
You're very welcome!
Thank you so much, Mr. Mario! You've been a really great help in my math journey. 😁👍🏼

You’re welcome! Glad you found my video!
Super video! I applauded for $10.00 👏👏👏
in 8 minutes, he taught me what my teacher confused me on for 2 weeks.
I really appreciate your vidéos; it helps me understand what my teacher tries to make me understand🙏🏾🙏🏾😁
Happy to hear that!
Thank you so much sir it was very helpful
Thank you so much, very useful i could cry in my calculus 2 class fr :')
Glad it helped!
Thank you, this video enlightened me as the other videos not telling inverse functions detailed
Great to hear!
thank you so much this has helped me tremendously🙏🙏🙏
I'm so glad!
Thank youuu. You’re the Goat 🐐 ✌🏾
Happy to help
WOW! Thanks Mario this finally makes sense
Wonderful as always, thank you.
How do you not have a million subscribers, the way you teach is amazing.
Marc, glad you like my teaching style!
I swear, I'm learning better here than just reading these stupid modules which is so lack of examples
thank you good sir
Thank you
Hi Just wanted to say thank you for this amazing and helpful video. it really helped me thank you again :)
You're very welcome!
Thanks!! :)
Thankk youu so much
Explained much much more clearly than my teacher!
Best videos are in english. TYSM.
thank you so much
Welcome 😊
IT IS VERRY GOOD SIR
THANK YOU! I finally understand!!!
How do you find the angle for all numbers instead of what appear to be carefully picked ones for ease of demonstration?
Thankyou! I really needed this!
RubiMercuri well explained ✌️
You’re welcome!
keşke benim Anadolu lisemde ki hocalar da böyle mantığıyla anlatsa neyse ki böyle bir kanal var👍
keşke
thank you ❤
soo helpful:) thank you
Mario you are a lifesaver!!!
Glad my video helped you Arik!
thank u so much
You are most welcome

is it the same thing?

For arcsin and arctan when I Looking for the angle should I get it from pi/2 and -pi/2 or is only the positive pi/2 is included?
I mean when the question wants the value from (0,1) and (0,-1)
I came by here enquiring about the arctan series a finding by Leibniz.
You are a life saver thank u

@@MariosMathTutoring Aahhhhhh so that's why!! Now it makes sense! Thank you for taking the time too reply and explain it to me !! ☺️
You’re welcome!
ur the goat
tankssss
the goat
Thank you amazon for this
Thank you so much!!
can I resolve without using calculator arcsin(1/4)?
If it’s sin-1 (sq3/2) equals pi/3, could it also be 2pi/3?
No, because 2pi/3 would make it negative since the x value is negative
sir Why cant we take period of cos from 0,-π
what an explanation ❤...love this channel.. ✌..i subscribes...
Welcome to the channel Uchash!
@@MariosMathTutoring tnx a lot..teacher...✌
so now... johnny sin is teaching maths

It has to do with the restricted domain...i discuss this at the beginning of the video.
Great teacher Jhonny sins
I keep getting distracted by how this guy sounds so similar to mordecai man. YOOOOooooOoolooOOOOOOOooooOooOo
The video was good but i was looking for an explanation on sec^-1 which was not shown..
why is the first question -pi/3 instead of 5pi/3?
Pearlie, It has to do with the restricted domain. You may want to watch the video again where I discuss the restricted domain for sine cosine and tangent.
Hello guys. I am turkish student. Our exam is very Hard. Go studyyy
i am taking calculus right now, i dont remember these from 9th grade wth T-T
omg , i went to your website and you are charging 179$ :-/ for algebra 1 and 2 that's to much

@@meganterry3864 true that is why i paid for it
@@ambientscience2951 Awesome! What'd you think?
