contourPlot(Finline, xMin, xMax, yMin, yMax, Clist, n)
An Mfile function that automates plotting contours such as those below:
\( (x^{2}  1)(y^{2}1) = C \)\( x \cos y  y \cos x = C\)

integralPlot(Finline, x0, xMin, xMax, n, plotFtoo)
An Mfile function that automates the plot of an integral of a function:
\( y(x) = \int_{1}^{x}{\frac{\sin t}{t} dt} \)\( y = \int_{1}^{x}{\frac{1\cos x}{x} dt} \)

directionFieldPlot(dydxInline, xyMin, xyMax, nXY, useArrows)
An Mfile function that automates the direction field plot of a firstorder ODE such as those shown below:
\(\frac{dy}{dx} = y(4y^{2}) \)\(\frac{dy}{dx} = \frac{x}{y} \)
