07 - Trig Functions of Acute Angles - (Sin, Cos, Tan, Cot, Sec & Csc Theta) - Part 1 - Trig Ratios

[@deirdreberger1363]

The synopsis of the “chopping function” and a deeper understanding is such an intuitive way to teach rather than just a book/teacher spitting out rules that can be easily forgotten. Understanding is a much more solid base than using rote memory.

[@MathAndScience]

I really appreciate your kind words!

[@tenwalls2428]

Freakin amazing. In 37 minutes I've actually learned this material. In high school and college I just memorized the formulas long enough to pass the tests. Again, this is amazing. This is exactly why our schools should offer both in-person and online classes for math.

[@patrickbutler165]

This guy is amazing.

[@dreadesina5216]

That was the light bulb moment for me....Sometime when learning all you need is one clarity that align with your reasoning and bam all door become open. This is why it's good to always pay attention and pick up points that you can use to connect a line to unlock your reasoning all you need is one Domino and the rest will fall.

[@tomeaston1844]

You take a complex subject deconstruct it and explain it in a way that makes the whole very lucid and comprehensible . That's a special talent.

[@braverudy]

Just brilliant, after 25 years, i finally understand the WHY; you are a genius as you explain complex topic in such an easy way to undertand

This is just amazing, as a year 8 student learning trig functions and other stuff, he helped me more than any course I would ever take. He is the only one I watch as math and science other than freesciencelessons AND I understand. Freaking amazing. You are the most underrated content creator I know

Jason is the real deal, I've not met any other teacher who can (and does) explain things in a way that is real. Others are great and know their stuff, but Jason takes math and science to a much higher and deeper level. Jim Trig

I like to remember the trig functions like this. Each function needs a buddy. A CO-conspirator or a COpilot. So sine has COsecant. COsine has secant. Tangent has COtangent. There's only one CO in each pair.

[@TerryJLaRue]

This was an excellent presentation. However, for the trig functions, I prefer the Super Hexagon by Don't Memorise (not memorize). Anytime I have a series of trig problems even through calculus, I draw and label a unit circle, and a Super Hexagon. Everything is easy after that.

Please, give me information on where you based the expression ¨Chop Factor.¨ I have not been able to find a reference to it on the WWW that coincides with the use given to it in this video. The three referred meanings are: [1]verb_to cut (something) into pieces with repeated sharp blows of an ax or knife; [2]verb_to abolish or reduce the size of (something) in a way regarded as ruthless; [3]noun_a downward cutting blow or movement

I think, the chopping factor varies from 0 to 1 for both sin and cos functions in the first quadrant. Our thoughts does matter. If you think positive,you get along with it. If you think negative,you will embrace it. If you think too much,you end up with nothing. What does matter here is, how we switch gears from negative to positive ones.

[@MathAndScience]

Yes!

Perhaps you should view the entire lesson. Numerous examples start around 25 minutes, after the lecture portion. Thanks, Jason

[@homelesshendrix]

When you are 45 degrees from the equator on the equinox, the Sun is at a 45 degree angle at noon and is the same distance from the equator as you, and since degrees are 69 miles, that means the Sun is 3105 miles (45*69) above sea level, according to your math. So welcome to Flat Earth. You just proved we don't live on a planet.

[@MathAndScience]

Nonsense. The fallacy is assuming the Sun is the same distance away from the equator. It is much further away.

[@homelesshendrix]

@@MathAndScience I was not assuming anything. Triangles which have two 45 degree angles and a 90 degree angle, by definition, have equal length x and y sides, so it stands to reason the sun is the same distance above the equator as both 45 degree latitudes on the equinoxes, there is no denying this FACT, and you are not a mathematician if you want to argue it. Degrees of latitude are literally named after their angle to the Sun when it is above the equator. In fact, there are 180 sixty-nine mile 'degrees' of latitude between the Center of Earth underneath Polaris, aka the north pole, and 90 degrees South, aka the south pole, which means the South Pole is not a single point but a 71,800 miles circumference around the ocean and continents because the radius is 180*69. We live on a fixed, tangent plane where all things perpendicular are parallel to each other and there is no denying the fact the sea is level and on the same tangent as the land and the outer ice. The idea parallel lines converge below our feet at the 'center point' of so-called gravity is literally patented bullshit, There is only one up and one down. Any mathematician who suggests our world is hyperbolic is living in a matrix in their own minds. There is no holonomy, no parallel transport and no positive curvature what-so-ever. Use your mind for a moment. When they violated Euclid's 5th postulate, they invented space and none of it is real. End your career now by admitting the truth and at least you will have your self respect. Gravity is pure invention, as is general relativity.

[@homelesshendrix]

@@MathAndScience The 'fallacy' as you say, is assuming Earth is a spinning globe. The FACT is, the Sun is at a 90 degree angle to both the North and South 'Poles' on the equinoxes, meaning it's sine and cosine are virtually equal at that distance because the Sun is so low to the ground. So for accurate measure you would go to the 45 degrees North and South latitudes and see the Sun at a 45 degree angle at noon on the equinoxes. Stop pretending the sun is 93 million miles away, false notions such as that were all contrived to support the broken hypothesis that Earth is a Planet/globe.

[@MathAndScience]

@@homelesshendrix I’m kind of speechless at your ignorance. You seem like an intelligent person but refused to except modern theories. So there’s no amount of evidence I could ever give you to convince you that your delusion is incorrect. I would just simply say this, we have astronauts in space right now orbiting a spherical earth - that is what you call a fact. We sent space probes to every planet of the solar system and many of the astroids, and the laws of gravitation that we used to calculate the trajectories of those probes are completely congruent with our understanding of the size and scale of the solar system. I’m sorry that you can’t accept these facts, and really hope that one day see and understand the beauty of the universe that surrounds us as it actually is, rather than as you wish it would be.
