The potential barrier is defined by V(x) =
((A^2-(x^2)*(b^2))^0.5 where x is less than or equal to
A/b.
First we want to sketch V(x)
Then we run a particle into it wth mass m and energy E (which is
less than A). Now that we have run the particle into it we are
asked to derive an expression for the probability of penetration in
terms of D = E/A and sin (y) = bx/A.
Finally, we are to evaluate our expression...
Find the absolute maximum of g(x,y)=x^2+y^2-2y+1 on the disk
x^2+y^2 less than or equal to 4. Solve 2 ways, parametrization and
lagrange multipliers. Please solve using both methods!
A. Let f(x) be:
x+(12/(1-x)) if x is less than or equal to -3
x+3 if -3 < x and x is less than or equal to zero
ln(x) if 0< x is less than equal to 5
(x-5)/5+ln5 if x>5
answer and explain these answers
B. Is f differentialble at x=5? justify your answer by
evaluating the one sided limits of
lim as x approches 5 (f(x)-f(5))/x-5
Let [x] be the greatest integer less than or equal to x. Then at which of the following point(s) the function f(x) = x cos (π(x + [x])) is discontinuous?
(a) x = 2
(b) x = 0
(c) x = 1
(d) x = -1
The density of a random variable X is given by f(x)=(3x^2, o
less than x less than 1, or f(x)=0, otherwise Let Y=e^x (a) find
the density function of Y(b) find E(Y) two ways:(i)using the
density of Y and (ii) using the density of X
