A friend showed me this proof: Proof: 2 = 1 $$Let \space x= y$$ Multiply both sides by x: $$x^2= xy$$ Subtract $y^2$ from both sides: $$x^2-y^2= xy-y^2$$ Factor: $$(x+y)(x-y) = y(x-y)$$ Ca...

2016年8月23日 · What does a 2:1 ratio mean? A ratio is a comparison between two (or more) different quantities of the same unit. A ratio does not tell us how many there are altogether, only how their numbers compare. For example if the numbers of boys and girls at a hockey match are in the ratio 2:1 , we know the following information:

I need to prove that $2 \neq 1$ in an ordered field $P$ using the ordered field axioms. We know that $0\neq 1$ by axiom, and $2 =1+1$ by definition. We also know that $1 \in P$ and $1+1=2 \in P$ by...

I believe the proper definition of $i$ is $i^2 = -1$ and not $i = \sqrt{-1}$ as is commonly stated. It is useful in many deep areas of mathematics, but as a starting point, it serves as a solution to $x^2 + 1 = 0$. I recommend looking deeper into the theory of complex numbers, particularly the polar form. To help you understand further.

2022年11月29日 · In mathematics, a ratio shows how many times one number contains another. For example, if there are eight pears and six lemons in a bowl of fruit, then ratio of pears to lemons is eight to six (i.e. 8: 6, which corresponds to a ratio of 4: 3).
