I had never given like to any other video but I am giving it to yours because you deserve it. Thanks you cleared a very big doubt of mine. I ask this question from everybody but they just say that it is a formula and you have to learn it. (especially my brother)
th-cam.com/video/RzZHr9UAJG4/w-d-xo.html . prove that sin 30=1/2, cos 30=sqrt(3)/2 ,sin 60=sqrt(3)/2 ,cos 60=1/2 . . . i will be happy if you subscribe my channel ..
In trying to follow your math I missed why you went from 3/4 to the square root of 3/4? Wait I see it now. On the left it was always a squared till then.

+Emmanuel Albazi You could use the trig identities. For example, knowing sin(30˚) = 1/2, you could use the half angle formula to work out sin(15˚) and cos(75˚).
I'll be honest, I really hate trig because I find it very difficult and I don't find it interesting. You are making my experience much less painful, thanks mate.
I love this! Nice and easy to follow. Thank you so much for taking your time to explain this.

I appreciate that!
Thank you, I'm trying to re learn Trigonometry so I can understand the concept instead of just memorize the tables and this helped a lot!

Mindblowing.Awesome.Fabulous.Amazing
Respect!
Good video; nicely laid out and explained.
Thank you Wayne.
You just clear my..understanding...respect
Amazing visual proof, thanks for sharing.
you are so underrated i wish you the best
Thank you so much. It was really helpful.
Glad it helped!
Very informative, thank you so much!
Why did we turn the triangle anticlockwise
In trying to follow your math I missed why you went from 3/4 to the square root of 3/4? Wait I see it now. On the left it was always a squared till then.
Helpful video, tangent of 30 degrees is √3/3 though
Thank you. Yes but √3/3 = 1/√3.
Thanks this was very helpful!
very simple and excellent sir
Thank you.. This video helped me a lot!
You're welcome :)
Excellent !!! Thumb up.
Thanx u explained it very simply and easily
Most welcome 😊
I’m still confused cause I’m trying to solve for a weird shaped triangle with one 30° angle

You are a good teacher i am giving you a like in place of thanks
what about 90°??
See my video on the Unit Circle: th-cam.com/video/usi6zMQiVrM/w-d-xo.html
Great job 👍 bro
At 8:17 I am confused on how you simplified the square root of 3/4 into 3/2
square root (3/4) = square root [3*(1/4)]=1/2 *square root(3)
just write this down, you will get the idea about what I've written
Beautiful video master.
But i am thinking know. How to find sine and cosine of the other angles?
(Without using calculator)
+Emmanuel Albazi You could use the trig identities. For example, knowing sin(30˚) = 1/2, you could use the half angle formula to work out sin(15˚) and cos(75˚).
thank you master.
Emmanuel Albazi 😠😠😠😠
Thank you so much!
Given that Cos A=3/5 and sin beta = 4/5. Without table evaluate sin A, cos B, cos (A+B)
I'm a little confused by your question. Are you sure that the question reads sin beta = 4/5?
Excellent , simple and easily understandable way of teaching. 😊😀😃
thank you so much sir
but if i want to find the other angles if trigonometry ,then what i do sir piz tell me
thank u so much your are maths monster
Happy to help! Thank you.
Where is trhe Video In where to find exact Values of angles biegger than 90 Degrees? I don´t find it man.
why we take the sides of the triangle as 1 unit only. Can't we take another values?
we can surely take any value and the answer will remain same...bcz it will eventually be eliminated
I'll be honest, I really hate trig because I find it very difficult and I don't find it interesting. You are making my experience much less painful, thanks mate.
Great tutorial
Why sin = opp/hyp
Because that is the definition of Sin. This opp/hyp is a constant ratio under different angles, so we named this ratio Sin of a certain angle.

thank you :)
Excellent explantion
Sirji translet in hindi plz
Excuse me, why is tan 90 = infinite (∞)? tan 90 is approximately equal to -2.
tan(90 degrees) approaches infinity. tan(90 radians) is approximately -2. Always double check the mode of your calculator.
Thanks for sharing this . I loved the explanations
thank you so much for helping me to prove that sin 30 degree is equal to cos 60 degree
Thanks!! ❤
but tan(90°) should be undefined...
good video though
Yes, but in a sense for all valid angles within a right-angled triangle, the limit of tan() as the angle approaches 90° is indeed infinitu
बहुत अच्छा है ! Best
oh! my god i see first time.you are great.
belives or not this is my 3 AM video when im wake up.
Excellent
Thank you
I ant find why cos 0 = 1 .
Perfect.......👍👍
Godly man
Nice
This is awesome
very cool very cool
good good
