To understand if the question is related to permutation or combination, we need to find out if the order is important or not. However if it is not mentioned in the problem, we have to find out whether the question is related to permutation or combination.Ĭonsider a situation where we need to find out the total number of possible samples of two objects which can be taken from three objects P, Q, R. Sometimes, it will be clearly stated in the problem itself whether permutation or combination is to be used. Difference between Permutations and Combinations and How to identify them The absolute value or modulus of a complex number z = a + b i z=a+bi can be interpreted as the distance of the point ( a, b ) (a,b) from the origin on a complex plane. The complex number a + b i a+bi can be plotted as the ordered pair ( a, b ) (a,b) on the complex plane. When we use the Cartesian plane this way, we call it the complex plane. We can graph a complex number on the Cartetian plane using the horizontal axis as the real axis and the vertical axis as the imaginary axis. In a complex number z = a + b i z=a+bi, a a is called the "real part" of z z and b b is called the "imaginary part." If b = 0 b=0, the complex number is a real number if a = 0 a=0, then the complex number is "purely imaginary." No:11 SAQ complex numbers Complex NumbersĪ complex number is a number of the form a +ib , where a and b are real numbers and i is the Imaginary number, the square root of i is −1.
