..Some Important Relations
From the above observation, we find (i) sin A = cos B where A + B = 90 o \ Sine of an angle = Cosine of its complement sin A = cos (90 - A) o sin 40 o = cos (90 - 40) o = cos 50 o (ii) = tan A (iii) By Pythagoras theorem a 2 + b 2 = c 2..

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 - Area of a region, bounded by a geometrical figure measures the portion of the plane occupied by the region. When we talk of the area of D ABC, we mean the area of the region bounded by D ABC. We shall discuss the geometrical aspects of areas of some important figures like t..
Probability concepts and probability theorems
Introduction - In our day to day life, we come across many uncertainty of events. We wake up in the morning and check the weather report. The statement could be 'there is 60% chance of rain today'. This statement infers that the chance of rain is more than that having a dry weather. We decide upon ..
Bayes Theorem, Binomial and Poisson Distributions
Introduction - 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 probability. Baye's theorem is named after the British mathematician Thomas Bayes who published it in a ..

Baye's theorem is named after the British mathematician Thomas Bayes who published it in a ..Examples:
Derivatives are also used to trace the graphs of different functions. To optimise the value of a differentiable function of practical use, derivatives of the functions are applied. This chapter reveals with many more application of derivatives such as determining the relative error in measurement,..
To find the qth roots of a Complex number
One of the most important applications of De Moivre's theorem is to find the q t h roots of a complex number. Let z = x + iy be a complex number. Let z = r {cos q + i sin q } be its polar form. And z 1/q be the q th root of z. Through De Moivre's h..
