Man you got it all wrong! Sine is what your kid does at the bank when they want to buy a car and promises to pay for it, cosine is what the bank makes you do so they give your kid a loan for the car, then cosine error is when the cosine ends up paying for the car because the sine didn't make the payments. And that my friends is why a sine bar looks like a little car with a rear spoiler.

When public education is forced funded and education is mandated, it is no surprise the quality and usefulness goes down. Consider that many public schools are also daycare centers and indoctrinate siphoning funds away from real useful practical education. Consider universities mandating all sorts of diversity classes and such to get a degree. It is indoctrination coupled with a type of extortion. Consider people taking classes for what they want to learn are more likely to work to learn. Likewise when parents and guardians are involved with their children's education, the children are more likely to learn. School choice is a step in a better direction.

Having been married 4 times and this last one for over 20 years... I finally figured it out. I mean how to get your wife to WANT you to buy toys... I mean tools. Make stuff for her. It's that simple. Or in order for you to do something that she wants, show her how this new tool (insert any damn tool you need) will help you do what she WANTS you to do. OH, and it does help if you bring her to your working area and let her watch you do some magical thing like cutting a special thread on a small part. OH... I forgot to tell you. If by chance you are one of those who believe that opposites attract... that isn't love its lust. so... Hopefully you were smarter than I was and you only married once and she has A LOT in common with you. Then she will understand exactly what the hell you are doing and why. That way, when you say "Honey, how about we go to Woodcraft and look at the wood lathes." and she says..." How about we go to Woodcraft and buy a wood lathe." You will know you have chosen wisely... BUT... be damn sure you make stuff for her!!! Now. How did I get my first metal lathe? I had a great rifle that I loved but I found a South Bend 9A lathe that I wanted more. I traded. Here is the small lesson. If you sell something, use that money to buy something to replace it. Similarly, if you are going to trade something, trade it for something you are going to replace it with. I had a great rifle that my grandpa had given me so the ole 30.06 just wasn't needed any more. hence my new lathe. Good hunting!! OH, and in case I forgot to mention it... make stuff for her!!!

[@maxximumb]

The problem teachers face with this kind of dry subject is putting it into a context that students will be interested in and concentrate. Viewers of this old channel are interested in making lumps of metal different shapes. Tony can use applicable examples to show how it all works which makes the information bit more interesting and you engage more. In a class of 30 to 40 students, very few of them will have a similar set of interests, so teachers are limited in how to show what they are teaching in a real world setting. This gives rise to people saying 'when will I ever use this crap after I leave school?. In a job I had many years ago I had to help a guy set CCTV cameras up to monitor banks of slot machines for a couple of days whilst his assistant was out sick. Now how they used to do it was one would watch the monitor whilst the other would tweak settings and lenses on the camera. This seemed like a long winded way to so it. So I asked if we could try one camera my way, with that evening's beers riding on the success of my idea. I took the tape measure and measured the length of the bank on slot machines, the height of them, the height of the ceiling, and the angle of the lens' field of view. Then using a bit of trigonometry, worked out how far away from the machines the camera should be located, the angle from the machines both in relation to the ceiling and to the bank of machines. Armed with may calculations, I measured out where the camera was to be located and mounted it, used an old school protractor to set the angles and hooked up the cable. The only tweak we needed was to focus the camera and then agree to what time my colleague would be getting the first beer in. It took about 1/5th of the time they used to take and as far as I know, they're still using my method and enjoying longer breaks because they 'forgot' to tell our manager they found a quicker way to do the job. Even the strangest maths taught in school can crop up in every day life.

Nice simple explanation in a shop context. The use of the roundstock to keep the hypotenuse exactly the same when supported from below with a simple jack is pretty smart. I feel like I just watched a 3brown1blue video with really really good cgi.

A 26 min youtube video did a better job teaching me trigSHOP MATH than a year of study in high school.

[@QlueDuPlessis]

You only did one yeah of trig in High School? Back in the Eighties we had 5 years of High School and trig was part of the syllabus every year. (Full disclosure, I took Mathematics right through Matric)

I need to watch this video at least 4 more times. I have done a lot of machining in my trade over the decades without being formally trained and poor math skills. My desire to machine and create parts have overridden the skills I don't possess, and this lesson is incredibly helpful. Thank you for the lessons you teach.

[@dralexmclean]

That was GREAT Tony, always wondered what this was all about, very simple, very well laid out, even entertaining. Thanks

[@jaredrevard2885]

why the hell were you not my math teacher.... I finally get it now!!! Thanks Tony!!!

Now I finally know where sine , cosine and tangent are derived from. I wish my old maths teacher would have explained this as clearly as you just did. Thank you.

Yeah, lots of calculators use radians as the default.

First time I understand these concepts. Thanks for the nice explanation!

[@GooserFive]

It blows my mind that you(a hobbyist) are better at teaching math than my math teachers were... P.s. I dont normally comment but thought I'd thank you for all the laughs and entertainment you have given me over the years. So Thank you!

You Sir, have a gift for bringing life to dry concepts that should be the aspiration of professional educators everywhere but somehow isn't. Therin lies the fly in the conventional western didactic ointment. Anytime you find yourself at a loss for subject matter, a lesson like this would be appreciated. Thank you This old Tony.

A heat treated sine bar was a school project while I was apprenticing. I wonder what became of it. Great memories of making it bud. Many thanks fella ! We did our math with no calculators. A time gone by eh. Great refresher bud.

one of the coolest explanations EVER on this topic. i have brushed shoulders with many instructors in many schools of thought, college full time at 15yrs old, trade school in California, IBEW trade school in Missouri, Technical school in Tennessee, and now a deep yerning to learn machinists theory and protocals considering all the equiptment i have aquired over the years for 'pipe-dream' projects. i have never heard such perfect, easy to understand, examples of trig functions...ever. WELL DONE. thank you very much for your videos sir. Precise, reasoning, humor, examples, ect., perfect mix.

You actually have those functions on your phone--You open the calculator function, and turn your phone horizontal and the the screen flips to wide with the trig functions. The "INV" key will give you the arc functions. My phone is also smarter than I.
