Whenever people say that 2 degrees global average temperature increase is no big deal, I usually remind them that 2 degrees is the difference from regular body temp and being incapacitated in bed.
A^2 + B^2 = C^2 is known as the Pythagorean theorem. This theorem explains the proportionality of the 3 sides of a right triangle (a triangle with 1 corner angle = 90 degrees). If you know the length of 2 sides (in his example, the wall beams) you can find out the length of the third (in his example, this would be the supporting strut spanning the beams that meet at a 90 degree angle). If their example is explaining a beam that spans the room from 1 corner to the other, you still use this formula as a rectangle is 2 right triangles that meet along their hypotenuse (the longest leg of a right triangle, or the length you are solving for in this problem). The 2 known sides are the length/width of the room, and you solve for the 3rd side, your diagonal beam
Completely fair point, that I do not think I have the knowledge to speak on. On the Trigonometry Wikipedia page, he pops up a few times, and many trig identities are known as pythagorean identities. Perhaps its not fully trig, but was used as a basis to help discover trig? Without having the understanding pythagorus gave mathematicians regarding triangles, I would think it would be pretty hard to begin developing deeper math regarding said triangles
Squaring using 3+4=5 is one of the oldest relationships used by masons. don’t need a ruler, just a piece of string or straight edge. Pythagoras described the relationship on paper
I mean, you could just convert the Farenheit or Celsius degrees to radians like they were angle degrees. “Bake at 6.109 radians for 45 minutes” still can mean “Bake at 350 degrees for 45 minutes” if you accept the implicit Farenheit scale. Radians would still be ambiguous regarding the base scale used, but it’s as ambiguous as “degrees” is so not really an issue.
So I mean, there’s no real reason to do it but also no reason you can’t.
Not me. I went years without until last week I realised I needed them for a script that points an object at a target in Maya. Turns out trig is really fucking universal.
