Trigonometry Full Course

www.greenemath.com/
In this full course, we will cover all the major topics of Trigonometry. Trigonometry is typically part of a Pre-Calculus course. Here, we will learn about the six Trigonometric functions (sine, cosine, cosecant, secant, tangent, and cotangent). We will then move on to study the unit circle, how to graph trigonometric functions, how to work with trigonometric identities, how to solve trigonometric equations, how to solve right triangles and oblique triangles (law of sines and cosines), how to work with vectors, and then finish up by discussing complex numbers in Trigonometry.

You don't know how much I have learned from your courses in Algebra1/Algebra2/College Algebra and how much I have missed from school. If you were there 13 years ago, I would have been an Engineer/Scientist by now. I had so much trouble understanding the material in school. Sure, we had patrickJMT, but I didn't understand one bit from his videos, and the video format was all over the place. I am doing this to prepare myself for Linear Algebra and get on with 3D Engine programming.

Since when I clicked on it, nothing happened

Cool, is #142 your last lesson or do you have more for pre-calculus? Potentially limits?

[@Greenemath]

@MilkyWayGalaxy1000 There are quite a few additional topics that are going in as I work my way down. Maybe 10-12 additional topics, if I had to guess. I will probably put in a small section on limits at the end but I do plan to cover that topic in a very detailed way during a Calculus I course. If I can ever get the time to do it.

@MilkyWayGalaxy1000 I don't have any specific times for when stuff would be done. Currently, it's a bit hard to have enough time to grind out material on a regular basis. Here is what I hope to add to the course: Combination of Graphing Transformations, Graphing Polynomials, Graphing Rational Functions, Asymptotes, Linear Programming, Mathematical Induction, and maybe limits. This is in addition to filming all of the practice test solution videos which take a very long time to create.

sir may I ask abt the even functions of cos (-theta) = cos(theta) if we have -2π/3 as our theta wouldn't the cos of that would be negative as well since it's on the third quadrant

[@Greenemath]

I think you are misunderstanding the idea and getting caught up on the notation. We are saying that the cosine value for both will be the same. cos (-2π/3) = -1/2 (this angle is coterminal with 4π/3) cos (2π/3) = -1/2 cos(-2π/3) = cos(2π/3) from the even-odd identities In each case, the cosine value is -1/2, which is the same. Try cos(π/3) = cos(-π/3) on your own. What do you find is the cosine value in each case?

[@Greenemath]

#139, #141, and #142 haven't been created yet. Those are topics that are somewhat related to Trigonometry but more for Pre-Calculus. I am working my way down there but I have some additional topics to add before I can do that. I should be able to release a Pre-Calculus course by summer of 24. Provided A.I. can't just make a full course by that point. Did you figure out your question? The two angles were vertical angles so they have the same measure. In other words, they are both 97°.

Yes, I was able to figure out the question, I misunderstood what the question was saying bc it did not mention finding all its angles but rather just gave marked angles.

Now that I found my free maths professor where do I find my free physics professor?

[@Greenemath]

You can use Khan Academy www.khanacademy.org/science/physics If you prefer KZbin, then Organic Chemistry Tutor has a playlist: kzbin.info/aero/PL0o_zxa4K1BU6wPPLDsoTj1_wEf0LSNeR&si=DXN1oUJHegfjaIfc

This is boon for us

[@Greenemath]

Glad to hear you are finding the lessons helpful!

[@kaiba7756]

[@Greenemath]

Maybe in 2025 if I get some time.

[@chrisallen3750]

[@Greenemath]

Not yet, hope to soon.

WTH why the views are not 1 Billion?

[@Greenemath]

I don't think that's going to happen with a math video.

[@simpleman283]

It doesn't have subtitles

[@Greenemath]

It takes a while for KZbin to generate them for a video of this length. You can check back next week or watch the videos in order on my website. Those videos do currently all have subtitles if you need them: greenemath.com/Precalculus.html#trig-functions

[@hchfvngcfhb4898]

Am I the only one here who have plenty of time and generally bored? Math is fun!

[@Greenemath]

It's fun sometimes, it can also be very frustrating.

[@ImanClips695]

Homie sat for 22 hours teaching trigonometry

[@Greenemath]

The lessons were filmed over a period of time and then stitched together. Good luck with your studies of math!

[@matthewkonopka3012]

most people in 2023 dont knw that you can make money on amazon with this one simple tri.....skip ad

[@Greenemath]

I'm really surprised you aren't getting study pug.

[@v-hypertopic7757]

Bro

[@Greenemath]

Yes

[@BangYongguk-sf8ly]

Wtf 23h video?? I am gonna faint.

[@Greenemath]

Just take it one lesson at a time, good luck!

[@BangYongguk-sf8ly]

Thanks professor. But i am in 10th grade and trignometry is not so advanced in my book. So idk if i should watch the video and learn. I mean is it even going to be useful to me? But yeah this chapter was the most fun and interesting to solve.

[@Greenemath]

@BangYongguk-sf8ly This is a pure Trigonometry course, so it contains more Trigonometry versus an Algebra II course. It's really up to your situation to see if you need to go this deep. I would guess, probably not in 10th grade. It could be useful for Pre-Calculus, which covers Trigonometry in more detail.

[@BangYongguk-sf8ly]

@Greenemath Alright thank you professor. Honestly I will choose law or pre-med so i will not have maths. But honestly in the past year I have come to like maths. It doesn't feel like a burden but kind of fun because I am starting to understand it. Plus unlike other subjects I dont have to memorize much in maths except some formulae. But thanks again. I appreciate your hardwork.

Touchdown’s

[@Greenemath]

No idea what you mean.

[@Jacob-kb8hf]

Is it okay, Sir, skip Geometry and instead learn Trigonometry?

[@Greenemath]

I think it would be okay, however, Geometry is usually learned before you take Trigonometry.

[@user-xq8mk5qu8n]

Buy a textbook.

[@Greenemath]

You can use this free book if you want: openstax.org/details/books/precalculus-2e The Trigonometry goes from chapters 5 - 8.

[@blankjac4809]

2:38:31 sir, when i use microsoft calculator, arccos (2/7) is approximately 1,281044625. how do you get approximately 73,398? am i using the calculator in a wrong way?

[@Greenemath]

You are giving an answer in radians and we are working in degrees. Later on in the course, we will learn about radians and how to convert back and forth.
