Professor Liebler at cstate is the best teacher I've ever had in my life.

Michael Lalonde was owed money by Homer Simpson under the bed and fell into the eternal pit of hell for no reason at all and a heated argument arose which caused an avalanche, he made a giant leap across the ravine and just as he hoped he killed the bad guy and made it away with ...

I am looking for the following solution manuals:
Elements of Engineering Electromagnetics - by NN Rao (6th edition,

I'm having trouble understanding a particular passage from 'Options,
futures, and other derivatives', by John Hull.
In relation to the price of forward contracts with known income, he
writes:

the 2 curves are...
y = x^5 - 2ln(x+5)
and
y = x^3 - 2ln(x+5)

Can two infinite lines be called congruent?

How do you find the value of x in tan(2x)-4tan(x)=3?

Dear friend:
can you help me?
what is the volume of a '3-sphere_pyramid'(that is: with 3 points A,B,C on the surface of a sphere of radius R and the vertex O is the center of the sphere) with angle<OA,OB>=al(alpha),angle<OB,OC>=be(beta),angle<OC,OA>=ga(gamma)? And,how you deduce it ...

i am new to the group and i dono how to use it.
please help me finding the solution manual to
"Managing Engineering And Technology" by "
Daniel L. Babcock and Lucy C.Morse"

Apologies if this is an obvious question.
I need to solve the following matrix equation:
s = (D - alpha x A)^-1 x (alpha x sigma)
D and A are square diagonal matrices.

If f:(a,+inf)->R is in D(a,+inf) and Lim{x->+inf} (f(x)+f'(x)) = A
then prove that Lim{x->+inf} f(x) = A.
I said something like this:
From Lagranges theorem we have: f(x+1) - f(x) = f'(c) where c in (x,x

would you be able to explain to me how to parametrize the curve?
thank you

hellow dear friend
I'm a new member of this group,
would you send me the solution manual of Heat Transfer 9'nth edition
by J.P.Holman, please?

I have been assigned a project as part of my ordinary differential equations class to determine the relationship between linear systems of differential equations and fractals. I have found nothing, and so far the only thing I've found on the internet is links to math articles ...

Suppose you had a cylindrical pipe and cut in in half along its entire length so you were left with two lengths of pipe semi circular in shape. Now say you wanted to mitre these together at a specific angle ( like a fascia board on the gable of a house where the mitre came ...
