Display only TRUE in V1? - mathnovice - 11-22-2018 03:17 PM

I am playing around with perfect squares, cubes,..... and I want to only display true values in V1 of advanced graphing. Is this possible?

example: 11^x-5^y=-4 (2,3), (0,1) is true, most others is false. I want to see only true or search for only values that return a true. Possible??

This is exactly what the Advanced Graphing app is made for. Enter the equation as written, but use an uppercase X and Y for your variables.

Thanks for the reply, yes I got lazy in the question and cap X+Y. After more thinking on the idea, what I really wanted was a^X+b^Y+[0,1,2,3,4,....]=0

Some algorithm to find things like this: 3^2-2^3=1 or 5^3-11^2=4

See this page for clarity https://oeis.org/wiki/Consecutive_integers_which_are_perfect_powers

Thanks again Mark
