expand tan^-1(x+h) in power of h
Hello candidate,
The basic expression of tan^-1(x+h) in power of h can be expressed as the arithmetic sum of tan^-1 x + tan^-1 h/ (1- tan^-1x)* (tan^-1 h) which is the general form of expanding the expression.
So, if you want to expand this expression only in terms of power h, you will have to put the value of X equal to such a function that it affect the value of h in the expression, such as π/4.
Hope This information helps you!!
