    Is -4 multiplied by -4 equal to 16?

    The exact same way. -5(3-3)=0 (-5)(3) + (-3)(-5) = 0 -15 + (-3)(-5) = 0 -3 x -5 = 15 More generally -a(b-b) = 0 -ab + (-b)(-a) = 0 (-b)(-a) = ba

    Creating a Formula: Force of Gravity at Different Elevations

    According to classical theory, the force of gravity would be \frac{G m_1 m_2} {R^2} R being the distance from the centre of gravity. Since you want to find the force of gravity on a body elevated from the surface of the Earth by h ,assuming the Earth is spherical, the total distance...

    Partial Fractions: Solving Examples with a Novel Method

    Hi, me with my really old book again. This time , a novel way of turning expressions into partial fractions. It would be best if I show you the examples in the book : \frac{3x^2 +12x +11} {(x+1)(x+2)(x+3)} To express this fraction in the form \frac{A} {x+1} + \frac{B} {x+2} +...

    Is -4 multiplied by -4 equal to 16?

    If I understand correctly, you want me to prove that negative times negative is positive, right? -a(a-a) = 0 This statement is true since (a-a) = 0 Using the distributive law : -a(a-a)=0 -a^2 + (-a X -a) = 0 -a X -a = a^2 So, substituting 4 for a gives -4 X -4 = 4^2...

    Exploring the Possibility of h=0: A Fully Deterministic Universe?

    What if the value of h increases with time. Maybe the universe started classically with h=0 and becomes a quantum universe. crazy idea.

    Atoms, Black Holes and Singularities: A Historian's Questions

    If the singularity is infinitely dense, then the gravitational force of attraction at the singularity must be infinite right? This means that the force of attraction between the quarks is over come(since infinite force is what is neaded to break the force). That means that quarks can exist...

    Solving quadratics and factorisation of polynomials using calculus

    Actually , you can extend it to all polynomials. for a cubic equation with factors a,b,c The second derivative = 2!(a + b + c) for a biquadratic expression with factors a,b,c,d The thirds derivative = 3!(a + b + c + d) Similarly, for a n-nomial the (n-1)th derivative = (n-1)!( a +...
