anyone could help to solve this problem,
so, i have the mathematical expression (shown in the picture below), the limit of integration for b is set in the range from 0 to 1, because the variation of b value, then the value of c(resut of integral) will be different for each b.
Plus, I am only allowed to use Simpson's rule to solve the integration. And the main goal of this task is getting the graph of f(c,b)
