This was absolutely one of the best tricks that I have ever seen!! I'm in calculus 3 and have a hard time trying to keep up with vectors and such involving trigonometric basic angles but that will definitely help me! thank you so much!!
Great video man, I tried learning this trick in class but I had no idea what my teacher was talking about. Absolutely a phenomenal job explaining it. Thanks.
Thanks Mr.Billings! actually my prof wants us to memorize a table of values of sine and cosine of the whole circle. Thanks God I found this. Great job.
Very simple and well explained, I wonder why you switched hands though, you started 30 degrees with your right hand continuing on to 45 degrees on your left hand.
This saved my life for an exam I had today. Discovered this late last night. Everything started clicking after I could easily calculate the sins and cos. Exam went very well, had to thank you!
that's really helpful. before this video trigonometry table always scares me.. but after watching this i can memember them like back of my hand.. thanks sir.. really helpful.. glad i found ur channel
This is an amazing video teaching us the trigonometric values..instead memorizing them for lots of hours together. i could never remember this sin cos values bt with this it became easier to understand the values nd remember as wel.Teachers can really use dis kind of video in order to make trigonometry easier for students. This wil make an average child also understand rather mugging up d values and getting confused during exams. Really a cool video must b shared with all maths teachers and students which can save their lots of time.
For people asking about tan and the reverse trig functions... just remember that tan is the same as sin/cos (think about how it applies) and the reverse trig functions are just reciprocals of the functions talked about in this video (sin and cos)
+Madeleine Colonna Rationalise the denominator (multiply by root 3) to get squareroot(3)/3. In most cases if there is a surd (square root) on the denominator it should be rationalised.
Great video! Quick easy. Could follow along on my hand because the video was steady and the hand wasn't waving all over the place. Thanks so much...Aleida H! :) Definitely helped. I've been teaching myself trigonometry and other math concepts, using UA-cam videos. My approach is to watch a slew of videos and get different viewpoints, methods and tricks to understanding and memorizing the material.
YOU JUST SAVED ME HOURS OF MEMORIZING THANK YOU SO MUCH
Those of you who are asking about the tan values. just recall : tan = sin/cos .
Similarly;
1/sin = cosec and
1/cos = sec.
Enjoy!!!
+Fable Glory awesome stuff bro
1/sin is kinda like asin and 1/cos is acos.
-_-
Cot ????
Nice❤
Thank you!! for all your comments. This inspires me to keep making more videos for you. and keep helping my audience
