         can you please send me the solution manual for quantum
mechanics by david griffiths

I am able to solve the area of a triangle algebraically easily, but I am unable to arrange the formula in terms of "s," the semiperimeter of the triangle.
I am unskilled in algebra, but I suspect that "s" can be introduced by way of substitution using a formula whose terms include ...

Help on this one please
Find maximum value of C = 2x + y on the region determined by the
constraints
x + y <= 6

1) Consider a,b E R,a<b and f is a continuous real function of real variable in [a,b]such that
d^2f/dx^2 f(x)>0,whatever x part of ]a,b[.Prove that if
f(a)=f(b) therefor f has one extreme in ]a,b[ and tell if it's a maximum or a minimum.
2) Calculate

Hey all,
So I've seen Steven Fortune's algorithm for generating Voronoi regions,
but the algorithm (or at least the implementations I have seen) are only
concerned with finding the edges of the regions, so that they can do the

Greetings All,
       Here we go again ;)  I am not understanding why the following simplification is
wrong:
       (4 ^ 1 + √2)(4 ^ 1 + √2) = 16 ^ 1 - (√2)² = 16 ^ -1 = 1/16

Simplify cos(x+pi)
How do I do this with the addition/subtraction formula?

Sorry if this is the wrong group (you guys all seem way too smart for
this question) if it is please point me in right direction..
Basically, i plot a series of X Y
coordinates. I need to know the formuala for calcluating the x value

I have a set of points in a plane. I want to find an algorithm that creates a polygon which contains all of my points. Polygon does not have to be convex that is why I do not need a convex hull. Further, I need to ascertian the features of the region i.e. polygon such as general ...

I've been explaining various constructions to a
maths club.  I've constructed the integers as
equivalence classes of pairs of natural numbers,
where (a,b) == (c,d)  if a+d=b+c, and I've

We are students in American University of Sharjah (Marwan Aladdin and Hadi Aladdin)(Computer Engineers).. and we are working on a new Math Formula.
Our current research is in "Number Theory". We found a relation between Prime Numbers and we came up with a formula to GENERATE ANY ...
