In my recent publication on the H-function of two variables [4], the double integrals are evaluated by using the technique of known integrals. In the present study a very general type of double ...

The equation of a straight line can also be written in the form \(f(x) = mx + c\). This is called function notation and is just another way of expressing the relationship between two variables.
