Advice: Learn all the formulas and also keep this method in your mind. In case you get confused or forgot or while re-checking the exam paper use this method to do these. Because you cannot trust your brain especially in the examination hall where there is an atmosphere of fear and nervousness. So mark my words and Best of Luck for your career!! And Don't Memorize I love your videos. In the above advice I am not criticising but sharing my experience and ideas. The method you provided is just 🔥🔥!

I don't think this teaches anything. Why is there a seemingly 'circular' pattern between the trig identities and functions? This hexagon method is a good way to memorize things, but it hardly proves anything. I'd be sad if someone said to prove why it works "just draw a hexagon!" for trig identities, when the relations are more cyclical than hexagonal.

[@AnonymouslyForgotten]

YOU CAN USE THIS WITH DERIVATIVES! Though its a bit difficult to see, there are some noticeable patterns. Once i noticed these, I haven’t had trouble with these derivatives at all! You’re not gonna understand without writing it out. Its a bit complicated at first glance, but simple when you understand it. I just drew the hexagon (without the edges, only the lines in between. It looks like a x with a horizontal line) 1. Search up the trig derivative online. Write them down across a page. 2.Then under each function, draw the hexagon thing 3. trace a line from the trig to derivative using a different color pen. Do you notice the patterns? Take a moment to study it for yourself. Anyway, hopefully you understand this: I found these patterns: Obtuse angles create fractional derivatives, Accute angles create singular or multiplication derivatives Following the inner lines left into the center and out, will give negative derivatives. Following the inner lines right into the center and out, will give positive derivatives. Csc and sec repeat themselves in their derivatives. The derivative angles on the left are opposite of those on the right. Ex: following the inner lines, draw a line from tan to it’s derivative 1/cosx. The line went right in a obtuse angle, so it’s solution is a positive fractional derivative. Ex2: following the inner lines, draw a line from cot to it’s derivative -1/sinx The line went left in a obtuse angle, so it’s solution is a negative fractional derivative. The angle is opposite to tangent. Ex3: following the inner lines, draw a line from sin to it’s derivative: cosx. The line went right in a acute angle so the solution is a positive singular or multiplication derivative. Ex4: following the inner lines, draw a line from cosx to its derivative -sinx The line went left in a acute angle, so the solution is a singular or multiplication derivative. The angle is opposite to sinx. Ex5: draw a line from secx to to tanx (not the derivative) The line goes right first, and is a acute angle, so the derivative is positive multiplication. Since it is sec, it’s repeated. So, the derivative is Secxtanx. Ex6: draw a line from csc to cot (not it’s derivative) The line goes left first so the derivative is negative multiplication. Since its csc, it is is repeated. So the derivative is cscxcotx. Haha, I did not explain that very well, so I encourage you to try figuring this out yourself! The pattern could probably be simplified a bit. For instance, it’s better to say the top accute angles are singular while the bottom accute angles multiply something by themselves. But whatevs! I wish you the best of luck!

How u remember those all 🤔

Copy paste is a thing that exists (no intentions to hurt😅) ☠️☠️

[@sanatandharma48]

Bro imagine spending 8 hours on keyboard

[@Extrify_]

Now make a infagon for remembering all this

thanx for explaining in such a good way...........nice explained.....keep it up....very inspireable.....ur voice is so effective

Amazing technique! Lot of trig in just 13 minutes! Thank you!

[@Beginning497]

I would be the happiest person in the world if I saw this hexagon in my school days😭....u made 50%trig in one single hexagon bro awesome.....

[@HaldirLeao]

Just amazing. Million likes from Brazil!

[@Pushed2InsanityYT]

Pesos

[@adityakuswaha2813]

These formulae were the basic ones. Difficult formulae are of compound angles and conversations from product to sum and vice versa.

[@vikramaditya2699]

This is sufficient for CBSE learning class 10 students

[@priyankmehta6034]

This innovative idea is gonna help all..This is the best way..I was ramming everything..Now its 10times easier...Thanks!

[@CosmicShock]

Not a single second i get bored while watching the video thanks to u!!

[@user-bv5sq9dy7w]

Thank you so much 😭 you don’t understand how helpful you are!

[@InfinityLearn_NEET]

You're most welcome. We are really happy to hear that it was helpful for you. We are glad that you understood the concept. You motivate us to do better. Keep watching our videos. 😊😊

Best video in the whole universe 👍👍

[@AbdulWahid-pk3dz]

It's very helpful for many students who don't know other tricks like me Thank u for this video

[@AK-iz3qn]

By practing, I have learnt all this identities.👍🏻 Therefore use this super hexagon and keep practicing 💓 so that you will able to do all trigonometry without any help.✍🏻

[@justbled5207]

0:47 that looks like a cube if you focus enough

[@singapuramharshitha5384]

Super explanation.. only with one hexagon

[@supernova884]

Found this in quarantine....omg my luck of understanding trig basics just got way luckier....

[@abulkashem2859]

This was an interesting video and helpful for the students to keep theses formulae memorised. But can anyone help me that how these trigonometry formulae came into existence

[@rohanbind6510]

Is it OK if i memorise this video? It's sooo awesome btw.

Thanks you Rohan! Keep watching!!🙂🙂
