Find the areas of the regions enclosed by the following curves.y=x4−9x2+2 and y=x2−7A=□ (Type an integer or a simpl) (Type an integer or a simplified fraction.)
Q. Find the areas of the regions enclosed by the following curves.y=x4−9x2+2 and y=x2−7A=□ (Type an integer or a simpl) (Type an integer or a simplified fraction.)
Identify Intersection Points: Identify the points of intersection of the curves y=x4−9x2+2 and y=x2−7 by setting them equal to each other.x4−9x2+2=x2−7x4−10x2+9=0Let u=x2, then u2−10u+9=0(u−9)(u−1)=0u=9 or u=1x2=9 or y=x2−70y=x2−71
Set Up Integral for Area: Set up the integral to find the area between the curves from x=−3 to x=−1 and from x=1 to x=3. Area = ∫−3−1[(x2−7)−(x4−9x2+2)]dx+∫13[(x2−7)−(x4−9x2+2)]dx = ∫−3−1[−x4+10x2−9]dx+∫13[−x4+10x2−9]dx
