Remember:
Proof by mathematical induction requires the fulfilment of both the conditions (i) and (ii) as stated above. Condition (i) creates the basis for carrying out induction and condition (ii) gives us the right to make a general assertion or of an automatic extensi..
De Moivre's Theorem
De Moivre's formula, named after Abraham de Moivre, states that for any complex number (and, in particular, for any real number) x and any integer n it holds that The formula is important because it connects complex numbers (i stands for the imaginary unit) and trigonometr..

Introduction
.02 cm. The unit of accuracy required is hundredth of a centimeter. Therefore, only digit 2 is significant. The 0 after decimal indicates the magnitude of measurement. Therefore, the 0 after decimal point is not significant. .02 cm has one significant figure. To sum up the above examples: (a) For a..
