Important results in proportions are: Invertendo, Alternendo, Componendo, Dividendo and Componendo and Dividend..

Some Results of Subsets..

Given a, b, c and d are non-zero real numbers, we can deduce other proportions by simple Algebra. These results are often referred by the names mentioned along each of the properties obtained. (1) If then bc = ad This property is known as INVERTENDO. (2) If , then ad = bc This property is..

Prove that Null Set is the subset of every set Every set A is a subset of universal set U since, by definition all elements of A belong to U. Also the null set f A. The null set f is a subset of every set, in particular f A. By hypothesis, A f . The two conditions imply ..

a) Prove cot 2 q + 1 = cosec 2 q . We know that cos 2 q + sin 2 q = 1 ...(1) also Divide (1) by sin 2 q on both sides (sin q 0), then b) Prove that 1 + tan 2 q = sec 2 q . The following has to be committed to memory 1) sin 2 q + cos 2 q = 1 2) sec 2 q - tan 2..
