John you, are wonderful teacher of mathematics your method of teaching makes what is believe to be hard so easy.

[CG-my]

I've only known basic math. If only a teacher like you taught me math years ago. I would have learned everything. Thank you.

[louhunt]

To help understand, you should have solved the tree height problem.

I'm 53 years old, and I just finally learned basic trigonometry. Thanks 🍻🍻

[mike-ypuk]

I like the daily exercise for math. I invest about an hour a day and it's fun learning how math and everything known to man uses math to get accurate results.

[jszlauko]

Strange that you never applied all that to the initial tree problem. That would have been nice.
Also, why get into solving an example triangle with the Pythagorean theorem? It would have sufficed to simply say "the tree problem has one angle and the length of only one side, thus we cannot use the Pythagorean theorem as that requires knowing at least two of the three sides."

[truckeralvarez]

When you say 3/4 and the answer is 0.75, where in the triangle is that reflected, meaning if you could insert that value into the triangle, where would it be?
So far, I have not seen any teacher show the location of the ratio.

Good explanation of trig but did I miss the answer as to the height of the tree? That WAS the question presented!

[YnotDoit]

I like you explanation, except for…. The fact i dont have a calculator all the time on the job. So finding the angle becomes problematic. So how do i convert the .75 to angle.

I have another way to measure the height of the tree…
I stand near the tree, my back facing the sun and I place a stone in front of me, whose distance has to be the same as my height. When my shadow will reach the stone, the tree’s shadow will be equal to its height. It takes a little longer and it requires a few beers to kill the time, it it’s pretty accurate.

[MichaelHarrisIreland]

Thanks, interesting. ....from Ireland.

Sure it's easy to do on paper with made up numbers but in the field you need that piece of equipment to get that angle You know that piece of equipment that you quickly glossed over.

[robertarguello]

I wish you would have had your calculator available, so that you could have completed the problem WITH THE CORRECT ANGLE as the answer.

[robertarguello]

Hello, In solving for the angle of the triangle, you said that: "a calculator with trigonometric function buttons was needed or a Table of Values was needed to go any further!"... Why are 👨🏻‍🏫 you always without a 🧮 calculator when, it is necessary for you to have one? And since today is 🎄Christmas day, why didn't you solve the initial problem and determine THE HEIGHT OF THE TREE? As for the rest of the lesson, thank you for sharing!

[canadianbacon]

Are you sure you don't need to use spherical trigonometry to find the height of the tree because the earth is a ball?

[leroyzwane]

Honestly my question is why tan? Used to calculate that angle, why not sin or cos?

[KeerthanTelugu]

hi john ur teaching well man but even indians also seeing ur classes
so please talk like a spin bowler not like fast bowlers
😟🤌

[stephensmith]

If you really want to know the height of the tree, please deposit $35.00.

[bissyadav]

Then how is you call is video basic?
Because you are not showing how to calculate that without calculator?
My age is 47 years no I am doing BCA. I thought that your video will teach me a trigonometry basics. But I am not comfortable.
I am so sorry sir 🙏

[sharethepudding]

Probably the most useless video on the topic on the Internet you basically just defined what these things were, but didn’t show any basics at all why’d you hit record if you weren’t ready to give us the height of the tree
