X Y x=y2 y=x2 (1,1) (4,2) Figure 2 The area between x = y2 and y = x − 2 split into two subregions If we slice the region between the two curves this way, we need to consider two different regions Where x > 1, the region’s lower bound is the straight line For x < 1, however, the region’s lower bound is the lower half of the. Solution Steps y = x2 y = x − 2 Swap sides so that all variable terms are on the left hand side Swap sides so that all variable terms are on the left hand side x2=y x − 2 = y Add 2 to both sides Add 2 to both sides. In the twodimensional coordinate plane, the equation x 2 y 2 = 9 x 2 y 2 = 9 describes a circle centered at the origin with radius 3 3 In threedimensional space, this same equation represents a surface Imagine copies of a circle stacked on top of each other centered on the zaxis (Figure 275), forming a hollow tube.

 For this problem, we will use x = rcos(θ) y = rsin(θ) Substituting these into the given equation gives (rcos(θ))2 −(rsin(θ))2 = 1 ⇒ r2cos2(θ) −r2sin2(θ) = 1 ⇒ r2(cos2(θ) −sin2(θ)) = 1 (trig identity) ⇒ r2cos(2θ) = 1 (note that from this we know cos(2θ) > 0) ⇒ r2 = 1 cos(2θ).  That is the formula of x2y2= (xy)(xy) dvreddy54 dvreddy54 Math Secondary School answered What is formula of x²y² 2 See answers Advertisement Advertisement sahilverma sahilverma That is the formula of x2y2= (xy)(xy) i don`t know very well refer to.
