Consider the linear map D: P2(R) + P1(R) defined by D(a + bx + cx?) = (a + bx + cx?) = 6+2cx, dr and the linear map T : P1(R) + P2(R) defined by T(a + bx) = (a + bt)dt = ax + 3x2. Let a = {1,x}, B = {1, x, x?} be the standard bases for P1(R), P2 (R), respectively. We know from Calculus (a+bt)dt = a+bx. Compute [D] [T]& and verify this....

x'=r (1 - 2 / 2 x where r and K are positive constants, is called the logistic equation. It is used in a number of scientific disciplines, but primarily (and historically) in population dynamics where z(t) is the size (numbers or density) of individuals in a biological population. For application to population dynamics ä(t) cannot be negative. If the solution (t) vanishes at some time, then we interpret this biologically as population extinction. (a) Draw the phase line portrait...
