Assume f=f(x), g=g(x)and (f^-1)(x) is the functional inverse of f(x). (f+g)'=f'+g' (f*g)'=f'*g+f*g' product rule (f(g))'=g'*f'(g) compositional rule (f/g)'=(f'*g-f*g')/(g^2) quotient rule (d/dx)(x^r)=r*x^(r-1) power rule and applies for ALL r. where g^2 is g*g not g(g)
F. R. G. Heaf was born in 1894.
F. G. R. Somi has written: 'Misitu ni mali'
What is the ratio of two odd functions? Ans: f, g are odd func on the same domain D. Let r = f / g, assuming g non zero everywhere on D. r(-x) = f(-x) / g(-x) = -f(x) / [-g)(x)] = f(x) / g(x) = r(x), and so r is an even function.

As per Newton's Law of gravitation F = G * M * m/R^2 But also F = mg Thus, mg = G * M * m/R^2. In this equation m and m will cancel out to get the final result as: g = G * M/R^2.
The domain of f is x is R (if imaginary roots are permitted, and there is nothing in the question to suggest otherwise). The domain of g is R excluding x = 5 So the domain of f + g is R excluding x = 5 and the domain of f/g is R excluding x = 0

counter example: f(x)= arctan(x) , f:R ->(-pi/2 , pi/2) g(x)=tan(x) , g:(-pi/2, pi/2) -> R (g(x) isn't surjective) f(g(x))=arctan(tan(x))=x f(g(x)): R -> R Although, if two of the three are surjective, the third is surjective as well.

F = G*m(planet)*m(object)/(r^2) where F is the gravitational force G is the gravitational constant m is mass r is the distance between the object and the center of the planet g = G*m(planet)/(r^2) where g is the acceleration due to gravity.
