public abstract double f(double x)
```
  - fprime
```
public double fprime(double x,
                     int order)
```
    nth derivative of function at x. Base class calculates it numerically, but you could override this if you know the exact form. order=1 for first derivative, 2 for second derivative, etc.
  - integrate
```
public double integrate(double start,
                        double end,
                        int npts)
```
    Numerical integration of a function in the interval [start, end]. Uses composite Simpson's method. (override if you know the exact form)
  - solve
```
public double solve(double a)
```
    Uses Newton's method to find numerical solution to f(x)=a. (override if you know the exact solution)
