How to Solve Trigonometric Equations (Precalculus - Trigonometry 22)

[@mahmoudwahidi8873]

Professor Leonard. I've spent hours upon hours trying to understand the concepts of these things. I've seen countless videos of people attempting to explain the same things you teach me, however their methods are (for the lack of a better term) brain dead, and I don't mean this in an insulting way but there is no thought behind getting to the answers. However, with your videos youve answered countless questions I asked myself whilst learning this stuff. As a result, I thank you very much for your work.

Thanks Professor Leonard, this series was excellent review for Calc AB, and I aced my entrance exam thanks to your content! :)

[@justin6651]

Way better than my professors and the videos they have us watch. Thank you for explaining everything so well!

[@kabirnoori5043]

i dont know what to say. I didnt learn these things in my native language but now i am learning it in English, all just because of the cool teacher. thank you so much sir!

[@maddiegebremichael3257]

1:21:45 replayed that a few time. Really got me. I’ve been saying I’m not put up for this because of how hard I think it’s getting even tho I’m still in the Pre calc classes.

[@HunterNapier]

Dude, thank you thank you thank you. I wish all teachers were like this.

[@isaaclutz7639]

Thanks Professor Leonard!!!!! These concepts finally make sense after 3 weeks of trying to understand them!!!

[@JJ-uj1wi]

Thank you so so much! This really helps alot! When i just started learning trig, I was dreading too learn more about it, cuz I was only taught like "you have to memorize this, so that you can do this. If you know this( assuming we have master all the basic), you can do this..." But this series clearly explain what they are and how they work, I am starting to have more fun learning it, and looking forward where i can apply it using what i have learned!

[@ayrthhhn]

Finally trig equations!!!! So excited about this, thanks Prof!!

[@KaranSingh-xx5lj]

Probably the next best teacher after Richard Feynman...also the coolest teacher in the history of cool teachers

[@cabbotsanders-xy4nl]

😮

[@IsaacRobertoCordova]

Thank you so much, sir! It’s helpful for me. I’m just preparing for next semester to become confident.

[@HeHe-od9dh]

Thank you so much. I did better on my exams and quizzes. It’s a really helpful channel that Im glad I found it this year.

[@sachinprabhuram5765]

You're the first person who explained why I can't just divide by a function. Thank you!

[@mathsandsciencechannel]

Great video sir. Thank you for your teachings and inspiration♥️♥️♥️

[@matheusvivan3434]

Professor Leonard is saving my high school days

[@brianc469]

Holy this timing. I have a trig review quiz for calculus tomorrow.

[@mariolucchetti4221]

Bro same

[@georgesadler7830]

Professor Leonard ,thank you for another long and detailed video/lecture on How To Solve Trigonometric Equations in Precalculus/Trigonometry. Solving Trigonometric Equations is similar to solving linear/quadratic equations but the Trig Identities are useful in many cases. Pattern recognition is also very important when solving these equations.

[@ramsay2661]

what a good teacher thanks for the help (:

[@qwertymangoes6455]

W vid man saved me on my test tomorrow, (my teacher sucks).

[@ojingaj30]

BRAVO!!! Great advice at the end of the lecture!!

[@MohamedMahmoud-md3ki]

just came here to give you a like and comment and go legend

[@AliAsghar-qi5zu]

thanks professor leonard, your series was such a great series but dear sir i want one thing that you must start a new series of other higher subjects of math like vector analysis , graph theory topolgy, OR like wise i say that all just for our sir if you meke its such a great helpfull for us students

[@rwharrington87]

Great advice at the end.

[@sjaoenvf]

make the student find your error. great idea from a great teacher.

[@MrsEvans-es2fo]

I'm hoping this gets clearer but I'm still fuzzy at when we need to restrict our domain and when we don't. I understand, restricting domain is in relation to using inverses but this is still unclear in my mind. I'm hoping this gets cleared up over time. But you're correct in your video, because we spent so much time talking about inverses, it's hard to shift gears to using the full unit circle. :)

[@MrsEvans-es2fo]

*gets to 55 mins* OOOOH!!!! I get it now.

[@shreejinimavat6401]

THANKS FOR A EXCELLENT VIDEO

[@somasahu1234]

Add to the playlist!

[@elicubillo313]

you ARE A GOD

[@onemanenclave]

Prof do you have any exercise sheets we could do for each of your lectures?

[@SPARKONMOTIV]

You are really fantastic

[@yeetya3203]

Preparing for Calc1 kind of nervous. Professor Leonard how many more trig videos will there be?

[@kristertv2769]

dang this is what i actually need for calc 2 lol

[@poopookaka327]

Thank you sir!

[@emranabdurhman3749]

Thank you really you are a great person.

[@amaniyo]

THANK U SO MUCH SIR

[@scottmclearn6949]

Thanks 🙏 for a another great video, can you teach us Abstract algebra too ❤

[@elguigomafla]

first leonard thank you. how did you know at 44 min when subbing theter back in to multiply by 2 and divide by 3?

[@ReneilweRatau]

22:22 I'm confused whatever i do i get 15/2 can someone please help

[@aminakhaled3139]

Thank you. you look like john cena

[@aragorio]

How do we know when a square root gives us both a plus and a minus?

[@abdulazizal-jaber5332]

it always does if you take a square number, but if you restrict the domain or if you want the outcome to be positive, you take the positive one, if you want the outcome to be negative, you take the negative one.

[@Onyx90210]

Thanks Sir

[@Shashank_Shahi1989]

How many more videos in this pre calculus series ? Thank You for your videos 👍

[@aboqassim1166]

You take the answer of theta from the circle how do I get the answer if i don’t have the unit circle in the exam with me

[@lindsaybeauliere1445]

that is something you have to remember. theres a pattern to it and vids that help u remember. i recommend drawing it immediately when u get ur reference sheet if you get one at all

[@ReneilweRatau]

27:30 why didn't he add 4pi because its 2theta

[@grey4704]

professor Leonard can you make videos on linear algebra, would save my life plsss

[@Kakashi_Hatake36]

For solving the tan(3theta) why did he add 2pi to the solutions for alpha why didn't he add pi because period of tan is pi

[@wintermelon8268]

This is also what I am confused about.

[@octs609]

Because coterminal angles repeat every 360 degrees no?

[@hspcricket9437]

Nice sir

[@PirateKingZoro-u8f]

bro is jacked

[@harihus8122]

1:04:36

[@turntup1234]

is that a Jcrew sweater? I have the same one lol

[@christophercarleton3541]

“That’s kinda cool” yeah okay lol

[@ahmedalanbagi1416]

I am currently in math 333 last math i ever had to take thanks a lot i wish you have venmo posted i would like to send you direct gift( I already have a patron membership
