a)is the function f (x) = x exp ^(-x ^ 2/2) a proper
function of the operator d2 / dx2-x2? if so, what is the intrinsic
value?
b)is the function f (x) = exp (4ix) +exp (-4ix) its own function of
the operator d2 / dx2? if so, what is the intrinsic value?

Answer the following questions for the function

(0,1) to (-1,0)

. For the function f(x) = x 1+x2
(a) find the intervals on which the function is increasing or
decreasing
(b) determine the points of local maximum and local minimum
(c) find the asymptotes.

Write a MatLab function J = Jcb(f, x) that computes the jacobian of
the vector f of functions of x. Input f is the vector of functions
[f1(x1, x2, x3...); f2(x1, x2, x3...); ...] and inout x is a vector
of unkown x [x1; x2; x3;...]. Output J is the jacobian square
matrix of vector f.

4 in slope y intercept form

Write a user-defined function, in MATLAB, with function call
val=evalf(f,a,b) where f is an inline function, and a and b are
constants such that a<b. The function calculates the midpoint m
of the interval [a,b] and returns the value of
(1/2)f(a)+(1/3)f(m)+(1/4)f(b). Execute the function for
f(x)=e^(-x)*cos(2x), a=-1, b=3.
