To find the range of the function y = x ^ 2 / x ^ 2 + 1 (the square of x plus the square of 1 / 2 of x), I use x ^ 2 = Y / y + 1 to find the range of [0.1] Then I use another method to change the original formula to 1 / y = 1 + 1 / x ^ 2, but the result is wrong. What's wrong with this method? I know how to calculate it. I use the second method to solve 1 / 2, but I just can't figure out what's wrong with the second method.
