    Angles
AI Thread Summary
The discussion explores the concept of measuring angles in three dimensions, questioning how traditional angular measurements, defined in degrees, could be adapted to encompass a third dimension. The idea suggests that three-dimensional angles might be represented in units related to the area of a sphere, potentially divided by 360 squared, although the variability of sphere size complicates this. The conversation also touches on geometric shapes like cones and cubes to illustrate the complexities of dimensional relationships. A reference to "steradian," a unit for measuring solid angles, indicates a connection to existing studies in this area. Overall, the thread seeks to understand the mathematical framework behind three-dimensional angles and their applications.

Three Dimensional Angles?!?

ok, this is a stretch. I have an idea. If there are angles, measured in units of 1/360th of a circle. what happens when you add the third dimension factor. I thought it would be somehow measured in units of like the area of a sphere divided by 360^2 maybe. The problem with area is that it changes depending on the size of the sphere. Then somehow I'm picturing a cone and a triangle. This is most easily applied to a cube, if there are more sides the 2 dimensional figure made for the cone would change.

I would like to know if there is ay actualy study of what I;m trying to describe.

thanks that was pretty much exactly what i pictured in my head
 

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...

Thread 'Video on imaginary numbers and some queries'

Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...

Thread 'Unit Circle Double Angle Derivations'

Thread 'Unit Circle Double Angle Derivations'

Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...
