Inverses
Antiderivitives  Inverses  Quadratic  Derivatives Reciprocals

    As we know we inverse equations they are nothing but reflections over the line y=x.  The nice thing about NuCalc is it doesn't care if it isn't a function, it just plots the points and connects the dots.  So this is really just the original graphs all reflected over y=x.  At least the way I was taught to think about inverses was as inverse functions.  So in the way I was brought up we would have restricted the domain to everything above or below the vertex and then said what was left had an inverse function while the original parabola didn't have an inverse.  Due the reflection we could think of anything that didn't pass a horizontal line test ( crossed more than once ) wouldn't have an inverse.  That is why with a parabola we can limit the domain to have of the parabola and then we have a function.  If it won't pass a horizontal line test when you reflect it, it won't pass the vertical line test which is a graphic way to define functions.  ( For every x there is only one unique y )
