Trigonometric Identities: How to Derive / Remember Them - Part 1 of 3

In this video, we tackle trigonometric identities, providing strategies to derive and remember them without relying on heavy memorization. By focusing on key fundamental identities, you'll learn how to derive additional formulas such as Pythagorean identities, sum and difference formulas, and even negative angle formulas. Whether you're struggling to remember trig identities for the first time or just need a quick refresher, this video aims to simplify these often-dreaded formulas by deriving them from simple concepts. Join me in this exploration of trigonometry and make your understanding of these identities easier and clearer.

What You Will Learn:

How to derive trigonometric identities from basic formulas
Techniques to remember key trig identities
Insight into the relationships among trigonometric functions
Practical tips for simplifying trigonometry problems effectively

Hi all! Please post comments, questions and anything else on your mind in the comment section! While I try to answer as many questions as I can, there are more questions than I can answer by myself so if you are someone who might be able to help, please do so! The community is so much better when everyone is involved and helping each other out. Our strength is our willingness to help each other!
Also please feel free to like or dislike the video. Your feedback is always appreciated so that hopefully I can make my future videos the best possible! Thanks and happy studies!

In 13 minutes I have learned more about identities than I have in school in the past 3 weeks

I want to thank you SO much for this video. Trigonometry has always been my weakness in math. I'm now in calculus and we're currently doing derivatives of trigonometric functions. This review has provided me with such a great amount of confidence in this unit. THANK YOU!

[neootukile]

to all the tutors on you tube thanks, you guys are a big help.

[MP-wbsh]

wish my teachers taught me the trig functions this way rather than just telling us all to memorise them. Thank you!!

[RavenCelestia]

got an exam on monday, im looking for miracles

[TheCatMasterOfKnow]

With every year I go in math I feel more and more like an idiot. Everyone else seems to get it...

[A_C]

YOU ARE AMAZING! I mean that from the bottom of my heart. the only tutor I could find that explains the small nuances (which are usually the things that trip people up) so well!! Please don't stop making videos. You have a new subscriber :)

[hurrdurr]

Why do they not teach this way in school? All they teach is memorization which isn't teaching at all in my opinion.

[nursyazreenmahdzir]

watched all your 3 parts of how to remember/derive trigonometric function . they are all amazing and i can finally understand them very clearly . thank you for the great video !

For compound angle, I tell myself that cosine is selfish & crazy, only wants to pair with its own "species" aka a clone(tries to find words that starts with C), while sine is always sharing. For tan I know that if it's a + on the numerator, the bottom is minus, & vice versa, as for denominator I know by heart of its signature 1, minus or add the product of tanAtanB, respectively to its signs. 😂 Good video! It helped me on my Pythagorean identities, I was freaking out at first. I recall learning logarithm from this channel years ago, Now I'm back again! 😊

I don't know what I don't know anymore.

[AsteruxGaming]

Thank you so much. I've been struggling to remember these identities for over a year and a half. This video really helped me remember them. I really appreciate what you're doing.

[RexGalilae]

Your a hero for all of us who once gave up math in high school!! I just want to see your great channel grow even more!!

[juanvolvoturbo]

Calculus makes me feel like a failure in life.

[hniang]

i never really comment on any of your videos but I always watch your videos to study for my math exams. You are a great teacher. Because of teacher like you, I also want to become a math professor and do Phd in mathematics:D Thank you so much for helping all of us!:D 

[RyuHaruse]

This series literally saved me from the despair of going to college without knowing a single thing of trigonometry...
My sincerest thanks!

[kaileykeenan]

Thanks x10^10. You're clear and understandable. I'm taking an accelerated Trig class right now, and lets say...the teacher is a talking book. You are awesommeee

[SupremeFallenX]

These hidden relationships make memorizing the identities so much easier! Thanks Patrick!

Be my math teacher D:

I'm taking calculus 1 now in university. first we I begun studying the subject I was a dummy person. I forgot all these trigs, and I didn't even try to understand it where did they come from. now thank to you. I'm able to understand and solve calculus problems after memorizing them with understanding. 

Awesome!
