When I was studying in school, I think that I had missed some crucial explanations and I was clueless about how to solve such equations. I barely passed this topic, having memorized some basic formulas and writing them down. Today, at 28 years of age, I decided to look up what I had missed. It didn't even seem hard. Thank you for your work! I had struggled with what was written in the textbook for weeks, but with your video it took me only minutes. Awesome!

THANK YOU SO MUCH!!! This was really helpful I finally understand it now.
I missed this lesson in precalc today because I was on a field trip and this actually saved me.
After three hours of trying to get this topic, I was about to go mad because I couldn't understand. 4:02 into the video and everything is so clear. Thanks!
Thanks! That last problem helped me with one of my problems. I never saw the quadratic formula, I only the book said that.....
Aren’t the sides supposed to be 1, 1 and rad two on the 45,45 , 90 triangle?
your videos really help me...BRAVO!!!!!

Yes you are correct, I believe he made a mistake there
In these multiple-angle solutions, may n be negative? When there is 2 or more multiple-angle solutions, how do you immediately know when you can blend them into just 1 multiple-angle expression?
@ 2:45 the hypotenuse and legs for the 45,45,90 should switch values
Thanks for this amazing video Chemistry Tutor 🖤
Thank you so much! My teacher isn't doing a good job at teaching this online and this is going to same me from failing my test!

Should we not add πn to tan for the coterminal angles since the period of tan and cot is π.
I failed precalculus. But I still want to know what this is. The universe is interesting
For the tanx=1, you are able to combine the two answers into pi/4+pi(k)
Thank u so much!!! Could u maybe do trigonometric inequalities?
Another great video... Doing the lords work.
Great explanation for specific questions, but a deeper understanding of how to go about solving would have been more appreciated. I teach and tutor higher mathematics , I also look for vids to supplement my teachings with students. Some of your other vids are wonderful, my comment is strictly constructive criticism. Most of my students only need to understand how to solve the problem to complete their degree (and of course get the answer right). You would make a wonderful tutor if you haven’t tutored already. Cheers!

Sir, in your second example, I have two queries. The first is, is that the only method : dividing both sides of the equation by cos to work that problem, because I certainly did not do that. Couldn’t we have squared both sides as an alternative? Second, aren’t you not supposed to divide by a trig factor - in this case COS X,since you may loose solutions??? Please explain thanks.
This channel is gold
Thnak you so much bro u saved me ❤️
i know this video is from a long time ago, but how did you get the 2, root 3, and 1 at 8:10 when you were choosing which angle it was correlated too?

may i ask why you add 2πn to the results, rather than 2πk? I always learned it as 2πk. I know it doesnt matter but its a weird way of writing it for me.
