------------
A = s^2
-----
Not linear
Why?:: variable "s" is raised to the 2nd power.

If ,
Then,The above equation is aquadratic equation not linear equation.The reason is that quadratic equation is a degree two equation(i,e,the variable is in the power of two) but linear equation is always a degree one equation.(i.e,the variable(s) is in the power of one.
If it is in degree three,it is called cubic equation.
Note that all these belong to a class called polynomial.
