Verify.
1.(sin5x+sin3x)/(cos3x-cos5x)=cotx
2.cos(x+y)cos(x-y)=1-sin square x-sin square y
3.sec square x-2secxtanx+tan square x= (1-sinx)/(1+sinx)

I've been through the glossary of my chemistry book and can't seem to figure out the answer to this--all the definitions are slightly different.

Compounds comprised of the same number and kinds of atoms but which differ in their atomic arrangement of those atoms are known as:

a) isotopes
b) isomers
c) homologs
d) allotropes

Please back up your answer with a reference. Thank you! :)

how do u factor this completely i tried pairing em up

2006-12-03 10:53:49 · 6 answers · asked by undergroundburn 2 in Mathematics

For my masters thesis, i have suspended a large silica test mass on a loop of fine silk thread to isolate the mass from background noise.
Further welded to this mass is a silica slide. I excite the resonant modes of the slide using an electrostatic drive plate in a vacuum, and by measuring the rate at which they decay determine their mechanical loss factor. I am suspending the test mass + slide as a pendulum to reduce energy dissipation from the system. I am trying to find the right words to explain why suspending the system as a pendulum reduces energy dissipation away from the system, and reduces noise but i am struggling - please help!

For example, a science class is worth 4 points; mathematics is worth 3 points; History is worth 2 points; and English is worth 3 points. The values of the grade letters are as follows, A= 4, B=3, C=2, D=1, F=0. What is the GPA of a student who made a “C” in Trigonometry, a “B” in American History, an “A” in Botany, and a “B” in Microbiology?

Can you help with this one!? Thanks!
