AI Thread Summary
The formula for finding the volume of a trapezium is given by the equation: Volume = height * (top area + bottom area) / 2. This formula assumes the trapezium is a three-dimensional figure with parallel top and bottom surfaces and planar sides. The term '(top area + bottom area) / 2' represents the average base area. The calculation is valid as long as the sides are linear. Understanding this formula allows for accurate volume calculations of trapeziums in geometry.

Assuming that by "trapezium" you mean "a three dimensional figure having parallel top and bottom and planar sides", yes. Basically, '(top area+ bottom area)/2' is the "average" base area. As long as you have linear formulas (and since you have planar sides, this is linear) you can calculate an average like that.
 

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...

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'

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...
