4. Show that the set A = {fm,b : R → R | m does not
equal 0 and fm,b(x) = mx + b, m, b ∈ R} forms a group
under composition of functions. (The set A is called the set of
affine functions from R to R.)
What is an option delta? If delta is 0.5 what does this mean?
How does delta change when the option is in-the-money,
at-the-money, and out-of-the-money
A certain wheel is a uniform disk of radius R = 0.5 m and mass M
= 10.0 kg. A constant force of Fapp = 15.0 N is applied to the
center of mass of the wheel in the positive x-direction. The wheel
rolls along the ground without slipping.
(a) Compute the rotational inertia of the wheel about its center
of mass.
(b) Compute the magnitude and direction of the friction force
acting on the wheel from the ground.
(c)...
