I remember doing this in high school, but that was 30 years ago. I am glad this channel explains it well. My teacher I had didn't do as well. I got an A in the class, but I never really understood what I was doing. I remember looking up on a chart to find out the degree. Could you do a video explaining how that number is calculated instead of just using a chart? Thank you in advance.

@johntaylor5968 Год назад

Good intentions but hopelessly long winded. Makes it sound far more complex than it is. Norwegian kids have this mastered at 9 years old.

Pythagoras and then sin or tangent table. Learned that in my 7th year. So why is this even a subject 50 years later.

@argonwheatbelly637 Год назад

Ummm... you don't need Pythagoras, and you don't need a Sin table. You do need a Tan table, even the small ones at the back of a basic trig book.

@jonathanbush6197 Год назад

I dug out my slide rule to see if I remembered how. It took me a while to realize that the T scales were themselves the degree values, and the tangent value is to be found on the C scale. So T is the arc tangent of C, once you figure out which T scale is the appropriate one. I got more than 3 significant digits, but not quite 4.

Why do people always do triangles in most houses the walls etc are off square or off oblong which ya need to know the angles. This is too complicated

@GreytOutdoorsMedic Год назад

Is there a way to calculate the inverse tan without a scientific calculator, I am hoping there is a way to work out my latitude by measuring the length of a shadow at solar noon? TY.

@jamesburrows5404 Год назад

FOCUS ON THE WHY? I’m 59 and l agree w most of the posts…”wish l had him as a Math teacher.” Respectfully,kick it up a notch! If you want real IMPACT (however u want to measure it), spend an equal amount of time on what most students are puzzled by on WTF does it matter. Get people to love/yearn math/science’s. Show them how (examples) it impacts life as they would know it. That’s the magic! Again, at 59 with a smaller window of time, there’s a greater appreciation, a hunger for “ what l don’t know…but should.) 😉

@banjoman579 Год назад

@BAlavi-tl5sg Год назад

Not so sure about 30.96 degrees! Why? O = 3 A=4 H=5 is a known, given "right angle" triangle of 30, 60, 90 degrees. In this case, project the two triangles over (a=4 over A=5) where you can see the 30 degree triangle is inside, therefore 30 degree angle will be a larger number than the angle in question.

Remember in this problem H=√34 and still a right triangle

I was working with tool and die makers also . The owner said what are you going to do with a calculator but when he saw how fast I could figure things he required everyone to have one .

When he solves for the other angle let's see him prove it is a right triangle. In order to be a right triangle the hypotnus should have been 5 and the side that's 5 should have been 4
