Final answer:
To find the area of the parallelogram formed by the intersection of the four tangent lines to the hyperbola x² −y² =1 at points where the hyperbola intercepts the ellipse x² +2y² =4, you can start by finding the points of intersection and then use the formula for the area of a parallelogram.
Step-by-step explanation:
To find the area of the parallelogram formed by the intersection of the four tangent lines to the hyperbola x² −y² =1 at points where the hyperbola intercepts the ellipse x² +2y² =4, we can start by finding the points of intersection. By solving the system of equations, we can find the x-coordinate of the intersection points. Substituting these x-values back into the equation of the hyperbola, we can find the y-values. Once we have the four points of intersection, we can use the formula for the area of a parallelogram, which is base times height.
