Axioms : The self-evident truths or the basic facts which are accepted without any proof are called axiom..

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 . ..

Which multiplication fact could be used to find 32 ÷ 4? => 8 × 4 = 32 or 16 × 2 = 32 or 32 × 1 = 32 or I don′t know...

We know that one of the most important method of evaluation of indefinite integral is method of substitution. While using method of substitution to evaluate definite integrals, following steps are involved.We know that one of the most important method of eval..

Introduction - The word 'Induction' means method of reasoning from individual cases to general ones or from observed instances to unobserved ones. Many important mathematical formulae are such that a result is formed by some means which does not provide for a direct proof. ..

Introduction - Today graphics, tables, reasoning, estimation and prediction are playing a very important role in stating the facts in terms of figures. Statistics deals mainly in communicating facts and figures in terms of a method called statistical method. Collection..

From our earlier chapter we know that, in statistical experiments, if the events A and B are independent, then But suppose the two events are not independent, that is the occurrence of one depends on the occurrence of other, then how do we compute This can be explained by conditional prob..
