tan squared x +secx -1=0, x is in II quadrant.
a. rewrite in terms of secx
b. hence find the exact value of sec x

please treat x as theta, because i can't type theta so instead i used x.

6 years of engineer work after school, with a not so stellar GPA. I plan on pursuing an grad degree, have years of experience but these graduate schools seemingly hinge on GPA only! In the past six years I have acquired a wealth of knowledge beyond any recent graduate with a 4.0 GPA. does this not account for anything?

The cube is 20cm x 20cm x 20cm. Is there any way i can figure this out? I need the Cd for calculating air resistance.
My velocity is 4.42m/s, it is falling on earth, so density is 1.2kg/m3.

A mass point at r = 3i + 4j - 2k rotates with angular velocity w = 2i - 3j + 5k around an axis. Calculate the linear velocity of the mass point given that the units for its coordinates are in metres and the units for the components of the rotational velocity are rad/s.

You know how the last problem's the hardest? Well, this is mine:

_ CH3COOH + _ O2 --> ?

It's a single replacement problem I think. Idk how to do it, the teacher didn't say anything about combining 3 compounds/polyatomic ions in this type of thing.

Hey guys.

I know how to make most of the special characters like:

√║∫±÷×°π²≤θⁿ¹ˉ³öφΔΣ ≈

But some people have posted questions that have set operators like:

x ∈ S ∩ T

Does anyone know how to make these characters? I don't see them in the Windows character map.

Where does the energy which would other wise be transferred to sound energy go to when a bell is struck in a vacuum? I'm guessing that the bell heats up a little but I'm not sure, can anyone explain this to me?

im not sure how and i have a test tomorrow.
sample prbo: x=3cos(30)T
y=3sin(30)T
do you just do 3sin(30)T/3cos(30)T to find theta and (3sin(30)T)^2+(3cos(30)T)^2 to find r^2?
if not, please explain.
