complicated cas problem
I have 2 functions. The first is a staircase function:
f1=atan(cot(pi*x))/pi + x - 1/2 The second is basically, fermats equation...x^n + y^n = z^n I can prove it only needs to be true in the positive domain....so I can use: y = f2 = (z^n - x^n)^(1/n) If n = 2, this is a circle. So, I wanted to see where these 2 functions intersect as in: f1(x) = f2(x) I tried: solve(f1(x) = f2(x),{x,y}) and I only get an empty square brackets (matrix) as a result. Then I tried n:=2, and it tells me I have a bad argument. I tried z:=5 and I get the same result. How do I get the intersection of 2 functions like this algebraicly. I know when I plot these functions with the values of z and n above, that (x,y) = (4,3) is a result....when I look at the plots....so it should be easy to solve. ??? |
