Can’t believe I’m on UA-cam to learn something my teacher couldn’t teach me Edit: I watched other videos from other math help such as khan academy, Brian mclogan, and this one channel that’s like khan academy but this one was us the only one that helped me
my final exam for trig is tmr and 1/3 of the questions are just verifying identities, and i had no clue what i had to do due to the fact that the trig course i’m taking is all self taught, but this video explained it so well! i’m x100 more confident now thanks to this video! :D ty dude keep up the great work
Phew, I thought this is the end of my journey and fail in my precalculus... Im so happy to watch this. It's a huge help for me to lift my grades a bit higher this time. Thanks for this video😊
it seems like there is a pattern with students who have pre-calculus teachers who cant seem to teach this theory in class. Thank you, this video is a big help
Thanks for the explanation, although I'm usually a happy and bright student, once I started learning trigonometric identities I became frusterated at myself and unhappy with my inability to find out how to verify them. However because of your great strategy of trying to get it all to cosine / sine I'm sure I'll do great on tomorrows test, thank you.
Thanks man! I'm struggling with this concept because of the new schooling, we only spent an hour on this, and my test is atleast half of these. Hopefully I can bump up my mark :)
There are so many trig identities it can be tough to memorize them all. After using a few key ones, I find most people end up memorizing the Pythagorean identities, and the double angle identities.
It's difficult to say. I believe everyone should take as much math as possible, so a class that works in some Trigonometry with some Algebra sounds fun. :^D
literally makes no sense no matter who talks about it or how they do. never goes over the conceptual basis of the proofs and just assumes that you're going to do rote memorization for everything.
Hello there! Can you please help me prove this identity? Please, please 🥺 I have been solving this for 3 days now and I still can't figure it out. 1+sin (x)+cos (x)/1+sin (x)-cos (x)=1+cos (x)/sin (x)
Yeah I still don't know what you're doing. I don't see what this has to do with medical school....All I should need is basic multiplication, division, ratios, percentages, and proportions! Btw I'm just ranting because I am required to take a class that has nothing to do with my major and I can't understand it no matter how hard I'm trying!
Hang in there. By seeking out other sources to learn, you are making progress. When you get that medical degree, you can leave the trigonometry identities behind. :^D
That can make it feel like you are fighting with one arm behind your back, but there are some ways you can get sort of get away with this. Think of starting with what ever side is more complicated and work to simplify like in the video. When you actually have to write out the work, only work on the left side. If something was canceled out, you'll more than likely have to multiply by some unit fraction (think of sin(x) / sin(x) ). After doing this a few times you'll get a sense of how you can make the simple side more complicated by using these unit fractions.
Not quite sure where you are getting that zero, but I suggest taking this in steps.... (1/cosx) - (cosx/1) Get a common denominator by multiplying the second fraction by (cosx/cosx). (1/cosx) - (cos^2 x / cosx) Now we can subtract the numerators, and keep the denominator the same (1 - cos^2 x) / (cosx) Use a Pythagorean identity on the top sin^2x / cosx Its starting to look more like the right hand side we are verifying. Split things out sinx * (sinx/ cosx) Use the identity for tangent sinx * tanx This is the right hand side so we are done. :^D

AssassinJo Fortnite same, he explains clearly.
Thanks! That means a lot to me. :^D
I learnt 3 years worth of maths on UA-cam.
my final exam for trig is tmr and 1/3 of the questions are just verifying identities, and i had no clue what i had to do due to the fact that the trig course i’m taking is all self taught, but this video explained it so well! i’m x100 more confident now thanks to this video! :D ty dude keep up the great work
THANK YOU so much!! There are a lot of people unwilling to explain this, so thanks for not being one of them! Awesome video

thank you so much, I'm at the brink of getting a D in my precalculus class but I will pass this next test because of you
I know a lot of it will be because you are putting in the hard work to make it happen.
Keep on truck'n :^D
Did you pass?
How did it go? I hope you did well
Sulli Lilly got a C first semester and a C+ second semester :)
Austin Cali that’s a great improvement. Glad you did well!
Thank you for making these math videos, its amazing how your videos still help students even after 4 years!
Some are even older! As long as they keep helping people, I'll keep making them. :^D

As much as I hate this trig you did a good job explaining it thank you

The first place where this has actually made some sense to me. It doesn't even seem that hard now, when it was complete Martian before. Thanks.
Thank you for uploading this video, I finally understand how to do it.
Very detailed and easy to understand. Kudos!
You put this up so simply! Thanks you so much
THANK YOU SO MUCH!! I couldn't make sense of this at all! I am so happy I found you hahahaha
Nice teaching sir it's lot's for me
Thanks
Great video! You’ve done a fantastic job.
my brain hurts , its so hard to be like
yes 1 = sin^2x+cos^2x
when I look at the question my brain just go blank and its all alien to me
SAME
Thanks teacher you really helped me 💜💜🥰🥀🥀
I really like trig identities! Ty!
Thanks for uploading this video
Very good problems and method of solving
Great video!
I wish my math teacher told me to always write with sine and cosine
Thanks for this guide
Do I have to memorize my identities?
There are so many trig identities it can be tough to memorize them all. After using a few key ones, I find most people end up memorizing the Pythagorean identities, and the double angle identities.
I’m going to be a freshman do you recommend taking Algebra 2/Trignometry Honors or Algebra 2
It's difficult to say. I believe everyone should take as much math as possible, so a class that works in some Trigonometry with some Algebra sounds fun. :^D
MySecretMathTutor I got a teacher recommendation but I’m just scared that my gpa will get affected.
thank u so much
I can finally get over this
It takes a lot of work, but keep at it. :^D
Can u explain how u got tan^2x+ 1 after canceling out the sins and cos, like where does the 1 come from ??
I think it’s from the Pythagorean identities
literally makes no sense no matter who talks about it or how they do. never goes over the conceptual basis of the proofs and just assumes that you're going to do rote memorization for everything.
SO HELPFUL! Thank you!
can i ask question math i cannot solve the equation please....
thank you so much this really helped me omg
This helped so much
Hello there! Can you please help me prove this identity? Please, please 🥺 I have been solving this for 3 days now and I still can't figure it out.
1+sin (x)+cos (x)/1+sin (x)-cos (x)=1+cos (x)/sin (x)
1) "Know your* identities."
Yeah I still don't know what you're doing. I don't see what this has to do with medical school....All I should need is basic multiplication, division, ratios, percentages, and proportions! Btw I'm just ranting because I am required to take a class that has nothing to do with my major and I can't understand it no matter how hard I'm trying!

@@MySecretMathTutor Thank you. 😫 I've just been going through alot
My teacher will give me a 0 if I even touch the right side, so this didn't help very much

your life saver
you saved my ass so hard
never pass my add math before hope this video will help damn so stress
شسالفة شباب لازم اتابعه كامل ولا اسوي له سكب
Thank you sir
OMG THANKS THIS IS QUITE HELPFUL!!!!
you da real mvp
could someone help me out here? I don't understand how he got sec^2x from tan^2x+1 at around the 5:58 mark
Since tan^2x = sec^2x-1, it would be sec^2x-1+1 therefore the 1's cancel each other out. Hopefully this helped T_T
والله مدري لكن اتوقع عادي سوي له سكب لانه يوتيوب اصلاً ولااحط شي بذمتي وشكراً
😑 انت صرت وياي في A+
عند السوداني
1/cosx-cosx/1*cosx/cosx=1/cosx^2/0 surely!! please explain.
Not quite sure where you are getting that zero, but I suggest taking this in steps....
(1/cosx) - (cosx/1) Get a common denominator by multiplying the second fraction by (cosx/cosx).
(1/cosx) - (cos^2 x / cosx) Now we can subtract the numerators, and keep the denominator the same
(1 - cos^2 x) / (cosx) Use a Pythagorean identity on the top
sin^2x / cosx Its starting to look more like the right hand side we are verifying. Split things out
sinx * (sinx/ cosx) Use the identity for tangent
sinx * tanx This is the right hand side so we are done. :^D
My week Ness
upload linear algebra course as soon as possible
Thank you 😘
Nice video

I sense a hopless comrade. I hope you are doing well now.
This is bad 😂😂)(Mathematics)
He did a good explanation
Thank you sir
Thank you ❤️
