WebWe cannot be 100% sure that a mathematical theorem holds; we just have good reasons to believe it. As any other science, mathematics is based on belief that its results are … WebWhat we can say though, is that if it is true, then: x 2 ≥ y 2 x 2 − y 2 ≥ 0 ( x − y) ( x + y) ≥ 0 At this point there are two possibilities: either both ( x − y) and ( x + y) are nonnegative, or one is nonpositive and the other is negative. In the former case, x − y ≥ 0 x ≥ y. WebMath is a language of representation. That being said simple mathematics can be proven with physical equivalents.
