MR. Organic Chemistry Tutor, thank you for explaining and defining these important Trigonometry/Reciprocal Identities. I worked in Land Surveying and Construction and Trigonometry is heavily used in this field. All our radio waves and cellular phone signals are all Trig functions.

Well, well, well... Where can I even begin The Organic Chemistry Tutor? I'm writing to you not just as a fan, but as someone deeply inspired and appreciative of the passion and dedication you bring to each video you create. Your ability to demystify the complexities of math and chemistry has been nothing short of a lifeline for me. Before stumbling upon your channel, math and chemistry seemed like an insurmountable mountain, filled with intimidating reactions and bewildering concepts. But your clear, methodical explanations and your calm, reassuring presence made all the difference. With each video, what was once daunting became understandable, and I found myself not just learning but actually enjoying the journey through the molecular landscapes you so skillfully navigate. Your videos have been more than educational; they have been a source of comfort and confidence. Watching you solve problems with such clarity and precision reminds me of the beauty and order that science brings to our understanding of the world. It's like watching an artist at work, except your medium is the intricate world of molecules and reactions. I admire not only your knowledge but also your commitment to sharing it so generously. The care you put into ensuring that each concept is accessible, no matter how challenging, speaks volumes about your character and your dedication to education. Thank you for every diagram drawn, every mechanism explained, and every question answered with patience and insight. You've not only helped me ace my exams but also reignited my passion for chemistry, which I now plan to pursue further in my studies. Please continue making these wonderful videos. Know that you are making a significant impact, reaching and inspiring countless students like myself across the globe.
Love,
Aiden
P.S. Since I am such a big fan can you please blacklist Greer from all of your videos. 🙏🙏🙏🙏

I was so confused until I saw this video, you are a life saver!!

[sanopann]

the only way to help this guy back is to watch the ads that popping out on his video and I'm going to write this comment to all of his video for you to know you can help him back by just watching his ads

[melattesfaye]

Thank you so much but i have one quation 4sec²180⁰ what is the solution of this pls answer🦋

[fvanessagan]

Why do we need this if we can use the normal trig function??

[SUTAWORLDWIDE]

AT 13:29 The answer is suppose to be positive, he swapped the location of -7 pye over 6, so just make up as you solve and check the unit circle too. Good Luck, Math will get easier soon.

[nombusoshongwe]

Totally off topic, but I have a crush on your voice and wicked brain🙌🙌

[kapersad]

You are soooo helpful, thank you so much!

[SUTAWORLDWIDE]

WHY IS NEGATIVE 7 PYE OVER 6 IN THE SECOND QUADRANT, I THINK THERES A MISTAKE THERE 11:36

[runoutarun]

cam you explain me why we can't write that sin its reciprocal as cos ? 🤔🤔

[jmbmarts]

I'm stupid. I still don't understand anything 😭

[kentrafaelmondas]

Example: csc(4pi/3) why did we use the y coordinate instead of x?

[edbay]

I’m sure there’s a mathematical way to make this simpler. Theta fucks everything up for me

[dobladocess]

fyi 6:59 is wrong it's not the answer the answer is -2/3 he made a mistake in 1/√3/2 its supposed to be 1/-√3/2 and the answer is supposed to be -2√3/3

[omegasteve]

12:30 i found a easy way to get the degree
7/6 or 7 divided by 6 =
x 180 = 210 (to convert radians just multiply the radians by 180 i just transformed the fraction to decimal)
180-210 = -30, get absolute value
30 radians of 30 is pi/6 or 1/6

can you increase the audio level of your videos?? I have my audio at maximum and i can barely hear you.
