Interesting Exponential and Logarithmic functions

Exponential function:  Any function represented as f(x)=  is called exponential function, where a>0 and a . Domain of an exponential function is R, set of all real numbers and range is (0, ) because exponential function attains only positive  values.

Polar coordinate System and converting equations from polar to rectangular and viceversa

Polar coordinate system is a plane with Pole(point O) and polar axis  which is horizontal axis from point O. Any point P in this plane is assigned polar coordinates represented as P(r, theta) we measure theta as positive when moving counterclockwise and negative when moving clockwise. If r > 0, then P is on the […]

Complex Numbers (Not so complex)

A complex number is represented as a+ib where a is real part and b is imaginary part. The complex number a+ib can also be represented as ordered pair(a,b) and plotted as a point in Argand plane. In this plane horizontal axis is called real axis and vertical axis is called imaginary axis. Complex numbers
