How can I compute the 3rd edge in a scalene triangle if I know the other 2 edges and the angle between them?
Thank you.

I heard a while back of a common and well known system that was around that
allowed users to represent any mathematics symbol or constant on a computer
screen.
Not sure if this is the right group to ask, but does anyone know what I mean

hey teachers and experts
I have this extreme problem which took me 2 days to look over
There are 3 proof parts, a and b are easy to prove anyway
but I am stuck with problem c

"Find the sum of integers between 32 and 395 when all integers are divisible by 6."
Someone tell me that the result is 12,780
Is it true? and What is solution?
help me please...

I need the solutions manual for Physics for Scientists and Engineers
by Randall D. Knight.
I would really appreciate it if somebody could email it to me

I was searching for the solution manual for this book almost everywhere and I
finally found it here.
The book is: Mechanics of Materials - 4th Ed. by Beer, Johnston, Dewolf.
I need it as soon as you read this email. I need it in less than 24 hours, if

Does anyone have the solution manual for 4th edition "advanced

the how much you want to sell it.

I have a simple question:
If you have a nested sequence of intervals in R, why can't one of these intervals be the empty set ?
Thanks,

I'm sorry if this is not the proper place to ask graph theoretic
questions.
Theorems related to hamiltonian cycles (Bondy-Chvátal,Dirac,Ore) are
valid for simple graphs and I was unable to find a generalisation for

Express the following in the form z=Re{Ae^(i(wt + a))}
z = sin(wt) + cos(wt)
z = cos(wt - pi/3) - cos(wt)
z = sin(wt) - 2cos(wt - pi/4) + cos(wt)

i have a trapazoid of which i know the lengths of the two paralel sides and all of the angles, is there any way to find the perpendicular height

I've got an isosceles triangle ABC.  There's a line DE cutting across it which looks like it's parallel to the base BC, but we don't know for sure.
The question is, given that the diagonals BE and DC are of equal length, show that the quadrilateral BCDE is cyclic.
