Webx=sqrt (y) dy/dx (x^2)=2x so 2x=2sqrt (y) To know dy/dx at any point we just substitute. For example, X: dy/dx at (0.5 , 0.25) = 2 * 0.5=1 Y: dy/dx = 2 * sqrt (0.25) = 1 It seems OK, but remember: this is Parabola, so we have 2 points at Y = 0.25. And the derivative of one is (1), the derivative of other (-1) so we have 2 X for each Y.
