Matrices and determinants Chapter #1 Pdf Download
The matrix determinant represents a number. We get this value by multiplying it and adding its elements in a certain way.
A complex number is a combination of a real number and an imaginary number. A complex number is in the form of a + ib and is usually represented by z. Here a and b are both real numbers. The value ‘a’ is called the real part which is denoted by Re (z), and ‘b’ is called the imaginary part Im (z).
logarithm, the type or power to which a base must be asked to yield a given number. As stated mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logb n. For example, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8.
