The perfect cube forms (x y) 3 (xy)^3 (x y) 3 and (x − y) 3 ( xy)^3 (x − y) 3 come up a lot in algebra We will go over how to expand them in the examples below, but you should also take some time to store these forms in memory, since you'll see them oftenOne Time Payment $1999 USD for 3 months Weekly Subscription $249 USD per week until cancelled Monthly Subscription $799 USD per month until cancelled Holidays Promotion Annual Subscription $1999 USD for 12 months (40% off) Then, $3499 USD per year until cancelledX^3y^3=3xy WolframAlpha Volume of a cylinder?
Section 43 Double Integrals over General Regions In the previous section we looked at double integrals over rectangular regions The problem with this is that most of the regions are not rectangular so we need to now look at the following double integral, ∬ D f (x,y) dA ∬ D f ( x, y) d A where D D is any regionExpanding and simplifying, we obtain the depressed cubic equation y 3 6y=0 Solving the depressed cubic We are left with solving a depressed cubic equation of the form y 3 Ay=B How to do this had been discovered earlier by Scipione del Ferro ()(xyz)^3 (x y z)(x y z)(x y z) We multiply using the FOIL Method x * x = x^2 x * y = xy x * z = xz y * x = xy y * y = y^2 y * z = yz z * x = xz z * y = yz z * z = z^2 We now have x^2 xy xz xy y^2 yz xz yz z^2 Combine like terms xy xy =2xy xz xz = 2xz yz yz = 2yz Therefore x^2 y^2 z^2 2xy 2xz 2yz
