WebTo prove this equation non-negative, you will have to convert the equation in terms of perfect square form containing a,b and c. Now, a²+b²+c²-ab-bc-ca = ½ • ( 2a²+2b²+2c²-2ab-2bc -2ca ) = ½ • ( ... If a+ b+ c = 0 and a2 + b2 + c2 = ab +bc +ac, then it follows that 0 = (a+ b+ c)2 = a2 +b2 +c2 +2(ab+ bc +ac), or a2 +b2 +c2 = −2(ab ... WebIf a + b + c = 1, ab + bc + ca = 2 and abc = 3, then the value of a4 + b4 + c4 is equal to Byju's Answer Standard VIII Mathematics Factorisation by Regrouping Terms If a + b + c ...

My attempt: If one or two numbers of a, b, c are even then we're done, so we'll have to show that at least one of them is even. Suppose a, b are odd, then a 2, b 2 are odd, so a 2 + b 2 must be even. So c 2 is even then c is even. So a b c is even. Is this enough to prove it? WebAug 16, 2024 · According to this answer at stats.stackexchange.com, you should use normally distributed values to get uniformly distributed values on a sphere.
