= (2x^2-3)(2x^2-3) -{(2x^2+2)(2x^2+2)}= 4x^4-6x^2-6x^2+9 -(4x^4+4x^2+4x^2+4)= 4x^4-12x^2+9-4x^4-8x^2-4= -20x^2+5= -5(4x^2-1) or 5(-4x^2+1)
For both the two main subjects I intend on teaching in this platform, I highly recommend to my students to focus on the theory as a first step (this could be a definition, some notes, etc). So, by trying ...
Use the chain rule: dy/dx = dy/du * du/dxLet y = ln(2x^3+x+8)Let u = 2x^3+x+8dy/dx = d/dx (ln(2x^3+x+8)) = dy/du * du/dxdy/du = 1/udu/dx = 6x^2 + 1dy/dx = 1/u * (6x^2 + 1) = (1/(2x...
Pythagoras’ theorem is the formula used to calculate any side of a right-angled triangle. The concept is that the square of the hypotenuse is equal to the sum of the squares on the other two sides. Assign...
So to integrate this function we would need to use a method called Integration by parts that you may have come across in your studies.This is where we separate the function into two parts to make it...
