A little help with calculus cross section project?
So for a cross section calculus project I need to find equations that when combined make a tennis racket looking base. So far the equations I've used are:
y= +/- √(9((-x^2)+1))
y= +/- 1.81e^x
So my questions are:
*How do I make the equation so that the handle of the tennis racket does not look thin as a stick? So, how do I make the handle on both sides are not so close to the x-axis?
*Also, if it is possible, how do you stop the y= +/- 1.81e^2 right when it intersects with the "oval", so it doesn't go onto infinity?
Thanks for your help!
