- Sine, Cosine, Tangent, and all that jazz. But with slide rules!
Big side note! Probably the easiest way to use the Sine, Cosine, and Tangent (under 45 degrees) scales would be to align T with D and read off D rather than C.
Also, I misread the last calculation, which was more accurate on the slide rule than I gave it credit for. My fault.
For those who are unfamiliar, some German slide rules as well as some Japanese slide rules include the P scale (also known as the Pythagorean scale). The P scale is useful for reading the cosine of angles from 5.73 degrees up to 90 degrees.
This is great, I'm going to show this to my geometry students. Thank you!
Awesome! You sound like a cool teacher :)
One of my slide rules have two tangents scales, one going from about 5.7 to 45 and the other goes from 45 to about 84
Nice!
It is probably to about 84.3 to be exact :)
Hello! I was wondering what slide rule you were using in this video.
I'm not even really sure, it was my grandfather's. It is a Pickett slide rule with trigonometric functions. You can find similar ones on Ebay.
Where can I find that slide rule? Mine is different and doesn't have both sides.
Probably eBay is your best bet.
Sin 4 degrees is 0.070 (0.0697), not 0.068. That confused me for a while!
Whoops!
