Final answer:
To find the point on the parabola y=1−x^2 that is closest to the point (1,1), we need to find the minimum distance between these two points. By taking the derivative of the distance function and setting it equal to zero, we can find the x-coordinate of the point on the parabola that is closest to (1,1).
Step-by-step explanation:
To find the point on the parabola y=1−x^2 that is closest to the point (1,1), we need to find the minimum distance between these two points.
The distance between two points (x1, y1) and (x2, y2) can be found using the distance formula: d = sqrt((x2-x1)^2 + (y2-y1)^2).
In this case, the distance between (x, 1−x^2) and (1, 1) is given by d = sqrt((1-x)^2 + (1-(1-x^2))^2).
To find the point on the parabola that minimizes this distance, we can take the derivative of this distance function with respect to x, set it equal to zero, and solve for x.
By solving this equation, we can find the x-coordinate of the point on the parabola that is closest to (1,1). Once we have this x-coordinate, we can substitute it back into the equation y=1−x^2 to find the corresponding y-coordinate.
