RE: X^(1/3) plots differently than the cubic root of x
(04-07-2015 02:46 AM)Gene222 Wrote: I used the function app and plotted the cubic root of X and got a normal graph as shown in the attachment. However, when I plotted the equivalent equation of X to the 1/3 power, only the positive values of X and f(x) were plotted, as shown in the second attachment. Why was only half of the graph plotted for the equation X to the 1/3 power? Hi Gene222, the problem lies in the interpretation of the calculator. Most computational algebraic programs interpret the cubic root of X takes only real values, approaching both infinite and from negative infinity. When you write it Alternatively, the CAS may want to interpret it as the complex values of the equation. Look at the example I made in wolfram. Success is the ability to go from one failure to the next without any loss of enthusiasm. View PNG/JPG in your Prime |
